dyno testing wrong?
i had steeda udp installed today. got in my car and found a sheet of paper with a chart.
im thinking car was dyno tested or something., dont know much about the dyno stuff.
anyway i have a 2004 mustang gt, ive got the pulleys plus mac cai and flowmaster delta
force 2 catbacks.
here's the numbers on the sheet
max power 194.5@4750 rpm
max torque 230.4@3750 rpm
am i reading this wrong i thought a stock 2004 gt had 260 h.p.

RE: dyno testing wrong?
Those number are way too low a stock mustang shouldn't dyno less that 215 on anything even a mustang dyno. My guess is that it was from a part throttle pull.. or they were testing for something else.. like spark or a/f ratio etc.. and the power numbers just happened to show up as well even though they weren't what was being dynoed.

RE: dyno testing wrong?
You guys are also forgetting that simple things such as how the car is placed on the rollers can affect the numbers on a dyno. Latley I have seen threads on here where people have had their cars on dynos and they were run in third gear and other such dumb mistakes. Personally I am at the point where unless I know the dyno and the guy running it or it is a super reputable shop I just don't put much stock in the numbers.

RE: dyno testing wrong?
you alson have a mustang dyno and a dyno jet. a mustang dyno gives you lower (more true to life) numbers. don't put too much stock in to a dyno in my oppinion they are great for tuning. there are some many things that can change those numbers you can take a car put it on a dyno run it let it cool down to the same starting temp and the numbers will be different.
