I just got my car back from getting the trany rebuilt and a 2500 stall put in and I was expecting to get a nice little preformance boost. I have a G-Tech that I use to track my progress and basically I got nothing! I'm pulling a 6.1 0-60 and a 15 flat 1/4 mile at 98 mph with very little tire spin. With the exhaust work and the G2 CAI, I was hoping to get low 14's or high 13's. The car just doesn't seem to be pulling very hard on the top end? Any suggestions of things that might be holding me back? I would expect a bone stock car to pull better than this. Thanks for any advice.

 

When was the last time you did a tune up. Not to bash G-Tech or anything but I heard that the G-tech time is usually off by .40 or so. Also my friend ran a 14.2 at 99mph. so i doun't you are .8 behind by only 1mph. I know there's lot of unknown factors, such as elevation, weather etc. But still get to a track see what you get, and if you think you losing power, do a tuneup.

 

I have only put about 5K on the car since I got it with 71K on the clock. I would bet it has never had a new set of plugs, I've just been avoiding that job because of the stock exhaust manifolds. Maybe platinum plugs can't go 100K if it takes 11 years to do it!

 

Get some longtubes and do your plugs and wires when you put your longtubes on. That will wake your car up.
