Made it to SpeedWorks in Lewisville, TX this AM to test these two chips that I have. Humor me as I give some background. Hopefully, this will answer some questions. I'd rather not get into debates with those who sell these chips.

First off, both chips make the shifts tons better than the factory programs. I have been pleased with the way the truck drives. I had the original '99 Superchip program for a long time, and that's the one I ran the 13.20/103.3mph time with back in Feb. '00. Recently, I had it upgraded to the CUX1TRAC program. Awhile back I purchased a PSP chip to try. It was oustanding except for the tip-in pinging problem that has been discussed. This only occurs at low-loads in OD. Otherwise, its perfect.

Testing was done at the same dyno, same day, computer cleared, and 3 pulls were made with each chip to get plenty of back-up data. All pulls were made in 3rd gear. Thus, no bizarre spikes which are due to a downshift. All figures are corrected. I do not have a scanner that's operable, but here's the results.

There is no doubt which one is the CLEAR CUT winner on _my_ truck.

Superchip: 352rwhp/419rwtq
PSP chip: 364rwhp/444rwtq

Area under the curve isn't even close until the revs reach ~4900rpm...peak HP is at 5100 rpm using both chips. This is why there is only a 12hp difference in the peak, but below the peak, the PSP chip has an even larger advantage.

For instance, at 3500rpm, the PSP chip makes 25rwhp/25rwtq more than the SC. This type of difference is across the board til the rpms climb up over 4800+rpm. Then the difference gets smaller, but the PSP chip is always making more power.

One thing I found interesting is that there was no small "spike" at 4800-4900rpm on the PSP chip like there is on the Superchip. This also occurred when I tested the truck in stock form last year. Kind of strange. I don't know anything about that, so I can't comment. I don't discount the spike, but it was there on all the SC runs, all my previous stock runs, but not on any of the PSP runs.

I'm not slamming/praising any particular product...just reporting facts as they are on _my_ truck.

Wes,
Wow, very imressive. I having tried both produts can actually feel the difference between the two. I think its great that you took the time out to do the testing yourself. And report honestly.
Since were on the subject.. Any idea which program Sal sent you? was it a custom programming?

GREAT JOB

That's funny; I got the "spikes" on stock PCM and PSP pulls.

 

Hey Spiro...

I just have his basic '99 chip. It's a single program chip. I don't need something for 100+ octane fuel, etc. I have only had the truck down the strip 6-7 passes in a year.

I figure if I ever put nitrous on it, I'll need another program while running on the juice, but this single program is working great for me. It exhibits some very light pinging under very light load, tip-in throttle. Only in OD doing about 45-50. Once it downshifts into 3rd and thus gets under load, its fine.

WOT A/F ratios look excellent. It's interesting that the PSP chip actually runs a bit richer than the Superchip at WOT. No pinging from either chip at WOT.

Wes,
WOW, thats great for the standard programming . I think PSP has since improved their base program with a little more performance out of it. As for the tip in, I had it slightly also. It a very simple and quick fix.
I have also noticed that the PSP runs a little richer that than Superchip.Glad to hear you enjoy it.


PLEASE guys....no BASHING HERE...were just talking o.k.

 

Spiro

What was the fix ??

Doug

 

Doug,

I had this problem at the WFC, it was quick fix which required Sal to reprogram something.
Yes, the chip would have to be mailed back to the manufacturer for the fix.Unless they start to trust us with the software... LOL

 

Hey Doug,

From my understanding the fix is that the threshold for the knock sensor gets adjusted, and this eliminates the problem. I believe the stock programming of the knock sensor will only allow it to pull out ~3+^ of timing.

I haven't sent mine in yet, obviously.

Hey Wes,nice numbers.

Outta curiousity, what was your baseline?

I did not baseline it _today_ at this dyno. While the shop owner and I are friends and he would've let me stay there for longer, I only had time to do what I did...which was 6 pulls total, allowing a little cooldown in b/w (monitored this, too, so that one chip didn't have an advantage over the other).

However, when I ran it a year ago with ~1500 miles on the clock, it was at 336rwhp. I don't recall what the TQ was. I don't have the stuff in front of me right now.

Now, I have ~9000 miles on the truck and these mods:
-PSP inlet tube/filter kit
-PSP chip
-Mobil 1 5/30 synthetic motor oil
-Trans Go shift kit
-4x4 transmission pan

Obviously, the shift kit and trans pan have no affect on HP/TQ production.

Maybe I'll get some decent air again, like I did this last Feb. I am confident it will run 13.0x on stock F1s with identical conditions. I have yet to run the truck with the shift kit installed, and I know by seat of the pants it is quicker now.

Thanks for the kudos. I'm happy with it.

Mr. Tarbox:

I would like to take this opportunity to thank you for sharing and posting your results of the latest Lightning chip dyno test in a non-biased manner.

I, like yourself, have a 99 Lightning for which I have researched, filtered responses, and pondered cost, benefit, application, and end result of both chip manufacturers you tested. I did not exclude other manufacturers from my research, I'm sure they have fine product.

In no way is this an attempt to re-ignite the flaming chip war, just a simple thank you.

Wes,

Great. Thanks for the info

Ditto here Wes, thanks for posting the results. That pretty much matches my track experience with PSP and SC. Brian and I have about the same mods except for chips, when we raced a few weeks ago, I was .2 faster, almost identicle reaction and 60ft times, mine just pulled harder. Our one time race would "indicate" about a 10-15 hp advantage.
Just out of curiosity, was the 364hp a spike or was that a graduale curve at its highest point? A lot of the dyno's I have seen lately have a 10-15hp spike in them that everyone claims is the peak hp. To me, that little spike is worthless because you are only going to be realizing that hp for a split second at most. Jeff

I would agree with Jagc on this, when him and I ran at Dimwiddy, things were close, but there was an obvious advantage.

The times were:

PSP(Jagc) Superchip (Me)
1.973 2.049 60'
8.686 8.865 1/8
81.75 80.67 1/8 mph
13.505 13.766 1/4
101.32 99.59 1/4 time

R/T's are unpublishable

Anyway, it was close, but it seemed that Jagc definitely had an advantage. I just couldn't gain any ground.

My .02, I think the SC is a great chip for anyone that is looking to get better performance. Without a doubt, its a much greater truck. I don't have the PSP chip...yet...so I can't comment, other than above. There are people running low 13's & 12's with both, so it seems that it is luck of the draw, or fine tuning. I will be trying a PSP soon, so I will be able to evaluate 1/8 times.

If you want great service and a chip in a few days, call Mike T for the SC. If you want the PSP....well, we all have heard the stories.

Later

Jac,

No little spike at all. That's what was strange. When I dyno'd the truck stock a year ago, there was that little spike you refer to. When I dyno'd it with the SC, there was also the spike (although it is not significant). However, the PSP by far had the flattest and least "jagged" curve of any of the programs, including stock. It's incredibly smooth. Can't explain it.
