well if a GT gets about 233rwhp with just midpipe and cat-back. Id imagine the rest is made with his TB + P , predator Tune.

No. It looks like his Mid-pipe/Catback & TB/Plenum and his tune make 14RWHP.

good jorb , look into a upgraded torque converter if you want less power loss to the wheels.
249.. looks like your T/B+P, CAI, Predator make about 14rwhp

Honestly with a dyno sheet like that, its hard to accept anything that it says. Wtf is with the spikes etc?
We have been seeing some almost unbelievable numbers on cars that have almost nothing done lately. It seems that more and more dyno shops are succuming to the temptation to over inflate numbers to get more customers.
I would say there is no chance a car with just a tune, catback, x, and some intake boltons will make 250~ rwhp thru a auto tranny.

RE: DYNO RESULTS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
The spikes like that are from the auto tranny.. like has been said numerous times and no one seems to read it... [&:] cant exactly throw your auto in your 1:1 gear.. you let it slow down it dowshifts.... makes it a pita.
I had spikes on my dynochart kind sort of like the last big one.... made my hp jump quite a bit (hit 280 something on the third run on a spike that we threw out when we printed it). Turns out my MAF was dirty, needed to replace the fuel filter, and spark plugs were terrible.. looked like they had been changed right after the car was bought. It was getting really rough in higher rpms because of all that.. we figured out it was adding and retarding timing at random due to the spark and the a/f was all over the place.... if it leaned and added timing at the same time, I got a BIG jump.. or if it did the opposite I had a pretty big drop.. you can see it all through my chart. I replaced all those things within a week.. havent gone back but its waaaay smoother now than it was.

RE: DYNO RESULTS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
When I got my 03 Auto GT dyno'ed, he just put in 2nd for the pull, no shifting at all, nice smooth results, this is when all I had was the catback and K&N,,, everything else was stock and I had a tweaked rearend at the time from an accident, so maybe add a pony or two to make up for the added resistance of a bent axle tube, lol. I sure hope I have better #'s now with my added mods and a nice new STRAIGHT rear end, anyway, point being, to dyno an auto, I believe you should just keep it in one gear, not put it in D and let it shift itself
