After FINALLY getting all my mods together and carefully choosing a tuner (Sal at PSP) I made my way to the dyno to see what the 04 Lightning would put down. I'm pretty happy with the numbers considering it was 90 degrees in the shop and I only had about 10 minutes cool down time after an hour and 10 minute drive. My mods and results:

Bassanni Cat back
BBP
FTVB
JLP CAI ram air
#4 pulley (Sals)
Predator tuned via email by Sal

STD 390HP 491TQ
SAE 382.6HP 482TQ

How do these numbers sound? I'm in south Ga and was on a dynojet dyno. The truck has 2600 miles on it, si I havnt went to Mobile 1 yet. Also havnt changed my plugs yet either. The power curve looked pretty good and AF ratio stayed around 11.4 the whole run. I'll be emailing Sal a scanned copy of my charts, one is a standard dyno graph and the other breaks down you AF ratio per 500RPM increments.

 

I'd say, your right around where you should be
FAST............................

CONGRATS

 

Next mod . . . throttle body. I don`t care what anyone says, it`s another 10hp with the 4lb pulley.

 

I just recently when to the dyno and SAE I made 394 hp but I had a below 10.00 A/F the hole time! so I told sal & the next day (emailed him at like 8pm got it at 6am when i woke up!) Tried it out and oh ****! its hauls *** now.

 

I'd put big bucks that you are wrong..

Anyway, for that much bank I'd be looking at porting the eaton next.

Ported Eaton is an idea, but I'm looking for cost effective bolt ons for now. I want to be able to remove the mods for re-sale when the new Lightning comes out.

 

?

 

To Date it's still one of my Favorite Mods, def an immediate noticable diff, especially in low end/ mid range throttle response.
EVERY MOD IS A PART OF THE BIG PUZZLE / PICTURE


(Mine droped off @ 4800 RPM)


AN A/F of 10
at the end of the run
when the most stress is being put on my Motor
@116 MPH
Using Nitrous

This might seem like a dumb question, but what is a FTVB? I see it in a lot of mods lists. Is this a Trans Valve Body? If so, who makes the best?

Great dyno numbers by the way.

 

Yes it a aftermarket valve body....

Who make the best....FTVB aka Factory tec..aka Greg evens.
The Level 10 VB that JLP carries is very nice also.

 

Nice #s.. I'm sure w/ a dyno tune you can squeez some more out of it.
Thats were I was with a JL mail order tune.. Now I'm at 404hp and 508tq after JL dyno tuned it.
