and every dyno reads a little different. My 02 was in the mid 180s and torque was around 125 or so. I am in Florida and it was near 100* F and I had a big drive to get there. The tech that operates the dyno can make things look good or bad for you as well. My next time there with a Spoon TP and K & N filter was 192 HP outside temps were about the same. I dynod with a group from our local S2KI community and there numbers were consistent with mine.

To callaesthetics with the 03 that hit 200 Hp stock, congratulations on a nice run, this is an impressive number for a stock AP1

I dynoed mine stock earlier this year (I think) and my peak horsepower was 212 and my torque was in the 130s. My dyno was done at night (Probably low 60s) and I don't know what kind of dyno it was. My car was dynoed for free at Rev'd up Customs and each pull had progressively higher numbers.

I don't know how accurate these numbers are and don't really care. The horsepower and torque curves were pretty linear with the jump at VTEC and then the power trailing off at around 8600 RPMs.

I would post the sheet but I don't know where it is.

i put down 197whp/131 stock. some of you other AP1 guys where in the 180's? on dynojets/mustangs?

My '02 with Spoon Intake, Filter, and Header with a Mugen exhaust at around 100 degrees, put down 187 on a Dyno Jet. I had a VAFC that day but the A/F sensor was broken. I never ended up going back to have it tuned. I wonder where I would have ended after a tune.

Nice numbers.

If the engine were stock on a MY01 would there be much differance if the ECU were changed out to a MY03, and if so where would the changes take place?

I believe that on the 02 and 03 model ECUs, the air/fuel ratio in VTEC is more lean.
