I bought my ITR about 2 weeks ago. It has 41000 miles on it. It came with AEM CAI, DC sport headers, and NGK plugs and wires. I got it from a major Honda Dealership here in VA. I took it to get dyno'd today thinking that I should be putting down at least 180 hp. So I put it on the dyno and I pull 138hp 100tq on the first run and 150hp 106 tq. WTF is that shit. They told me that the air fuel mixture was not correct. But talking to ABACUS racing, they said that was a normal fuel mixture. Man does my motor suck that bad. I am going to take it to let another shop look at it and see what is going on with it. This was on a dynojet not a mustang dyno. This is a graph of the pulls. What do you think? Any information would be helpful.

 

what was the A/F ratio?

what rpm was peak power achieved at?

timing?

seems that you are missing 15whp somewhere.

definitely do a compression check.

also, the ECU might be pulling timing for some reason...thermostat might not have opened..

Next time you dyno, make sure the engine is hot between pulls, I'm sure you already did this.

I'm not too familiar with all-motor fuel calibration, but to me it seems like it's going lean in a few spots

 

do a compression check, change the plugs and wires, check the timing, put the timing at 18 degrees BTC on the distributer. if that all checks out call inline pro in springfeild VA(www.inlinepro.com) and get them to tune it for you
