I finally got my 2002 GT dyno tuned. my car has march ram air, jlt rai, 70mm tb w/spacer, upper plenum elbow w/spacer, u/d pullies, comp xe270 cams and springs, long tubes , catless x, magnapack cat back, sct x3,and 4.10s.
the final dyno run was 271.2whp and 305wtq. it was about 90 degrees that day but i expected around 300whp. am i wrong to think that or is the dyno out to lunch?! any input would be great.

With your mods I would think your estimate of 300hp is probabaly spot on. It wasn't by chance a Mustang Dyno was it? Both of the mustang dynos that I have been on have really low numbers.

^Yea that seems a bit low but I think they all run a bit different! numbers can always very from one 2v to the other with the same exact mods!

take in mind all dynos are different. tuning a car in 90 degree weather sucks. I dont have long tubes but i have a stage 2 anderson cams and some livernois heads and i made 305 on a mustang dyno in april. A year later in the middle of july on an 90 degree day i went on a mobil dyno jet and my car only made 285...

don't get too hung up on rwhp numbers. remember, a dyno is a tuning tool, that it. be happy that you know your tune is good now. take it to the drags to get some real performance numbers that actually matter:)
