Possible problems with engine, Lost power -.- HELP!!!
So here I am about to bring the car to the garage to do alot of work on it when I decide to take it to the dyno to get some baseline #'s after the UDP install. So my first numbers were 304.9 with 324.7 TQ on a dyno jet The A/F was 12.2. This was with CAI/Tune/Shorties/Xpipe/Corsas/still with cats and stock pirrellis. So I install the UDP's and take it to the dyno and it reads 295rw/300tq with a A/F of 13.0. The only thing different was the UDP and tires, I now have some falken azenis 275/40/17. I really dont know what happened and am holding out to put the other parts in till i find what the problem is. Also I did a dyno inbetween those 2 with a 255/50/17 tire. The dyno is a dynojet and all passes where on the same dyno.
Any ideas help please.

If the dyno passes were not somewhat close together on the same day, you are in a panic about nothing. Just a weather difference can make a 10hp difference in a dyno pull.
Besides, HP numbers on a dyno mean basically nothing anyway. Time slips are a much better judging delta.

I have done over 60 passes on that dyno before that and no problems. The weather doesn't really change here in PR. it is 74-84f all year around

I'd bet anything those 275/40's weigh more than the pirellis, that should rob you of some horsepower. I wanted a wider and larger diameter tire in the rear, but after reading how much they all weigh I decided against it.
What was your dyno numbers with the 255/50's? I wasn't sure what you meant by one inbetween.
