I am not sure but my truck seems to be getting more powerfull by the day.

When i first brought her home, I thought she was kind of a slug also, but then I put in the psp 4 way chip and filter and I could see a bit of a difference.

Then I put in the bassani exhaust and I could feel a difference then also.

However all these mods were done in the 1000 - 1100 mile range. Now I have almost 1600 miles on her and she is much more power full than even several hundred miles ago.

Even with those mods just after they were done I could not get her to spin the tires. I know spinning the tires doesn't make you quicker, but I like to show the kiddies running around here what kind of smoke show it can do.

Now today I took her out and had the ac on full blast and decided to launch from a stop light hard because there were some kid in a GT checking out the truck hard. So I nail it and of course forget to shut off the ac and it spins the tires for probably 20-30 feet. This is the first time it has laid down a patch like that from a stand still and no braking, just from brake to gas. Oh, it also lays a nice patch of rubber when it hits second.

The only two things I can think of that are making more power are:

1. the engine is getting loosened up more and therefore making more power.

2. The chip's program is coming in more or something like that. ( I do not know that much about the computers in these things and have heard some say that it takes some miles to get full benefit from the chip)

All I know is that this truck is really coming on more.

Oh and by the way the temp was 88 degrees and the humidty was 17% and I live at 6300 feet altitude.

i have a diablo chip, jl power cooler, top and bottom pulleys 80mm pro-m(thats for sale) and 10.5 m/t et streets and a few other thing that i can't tell you at this time (hush hush wink wink)

 

pgio, as your tires get the "new" worn off, they are easier to spin. All the tires I have experience with are like this. My 2000 L will spin easier with just the gas from a stop now at 4000 miles, although it has always been able to light them up from a stop without any power braking.

My S-10 4.3, 5-speed does it real bad too. As the tires get worn a little, it becomes easier and easier to spin and gets down right ugly when it rains. I just put a new set of Touring T/A's on the S-10 and I am back to having traction for a little while.

About 2 months ago before I got new tires, I scared myself grabbing 2nd in the S-10 going around a corner. I hit some oil and got totally sideways. I just put the opposite lock to it and kept on getting it. Good thing my wife wasn't there.

 

A couple of other people have already answered this accurately. It's all in the 60ft time. My Lightning pulls pretty consistent 2.00s on the stock F1s. The 13.110 was with a 2.08 60ft. I have never done better than a 2.3 60ft in the Camaro. Comparing timeslips, the Camaro actually does the last 1/8 mile of the 1/4 mile over 1 second faster than my truck. Between the Camaro's lousy 60ft times and the truck's aerodynamics, I think the reason for the disparity between ETs becomes clear. The Z28 with a 6 speed is very difficult to launch on the stock Goodyear RSAs.

 

I made 7 passes Fri. pm. Had to leave the ET Streets at home due to scattered showers in our area. Ran several 14s; 14.442, 14.812, 14.251, and a 14..009 to a Indie 400 Camaro's 14.010.

Too much wheel spin--couldn't hook! Best of the nite was a 13.488@103.68--had a 60'@2.118 on another pass. Track closed early due to rain and LIGHTNING!

I was at the track last weekend and I have 10,300 miles on my L and I ran a best time of 13.91. I have no problem hooking on the street either.
