Well got my car tuned today and im pleased with the results. Thought id share
setup:
USDM ITR longblock (stock)
Professional Products IM
Professional Products 65mm TB
3" SRI w/ BPI stack
JDM ITR header
T1R resonated test pipe
2.5" Kteller piping w/Vibrant muffler
Hondata IM gasket
P2R thermal TB gasket
Tuned on Crome by Colombia @ Speed Clinic

Colombia said if I get a Hytech replica header and S2S2 cams that I should hit 200whp. I think ima do it.

lol.. Lots of people seem to like to post dynos now in "standard" hp instead of SAE. You can't really compare a dyno in standard to anything else really, hence the need for the SAE correction factor. I don't think many people realize this.

Florida and CA are at sea level. And our ambient temp is like 75 degrees. What exactly do you think dyno corrections are for? If we were 5000 feet elevated at freezing temps I could see a big change. I don't think many people realize this.
Dyno will record actual HP & TQ produced without regards for weather conditions and elevation/altitude/Air Density. It's only when one of the recognized correction factors such as SAE, STD, DIN, etc are applied that the actual numbers produced or corrected base on both weather conditions (temp, Relative Humidity) and elevation/altitude/Air Density are used to try and provide HP & TQ numbers that will be close to same when run on the same dyno or in some cases a different dyno by same manufacture at same elevation based on weather and absolute pressure conditions for that day.
Now in the case of a Dynojet Dyno, Dynojet says about 4500 ft above sea level is the max elevation their Dyno software can handle before the corrected numbers start to become skewed due to elevation, but they also say that regardless of elevation any correction factor above 1.3 will start to skew numbers higher also.
So if you see corrections factors in the 1.4 and above range you should consider that those corrected numbers might not be duplicable if you dyno'ed the car under better conditions that produce corrections factor of actual numbers in the .97 to 1.3 correction factor range.
Dyno's don't know are care what sea level is or for that matter what Absolute Air Pressure is when determining what your actual numbers are. The software used to convert those actual numbers to corrected numbers does.
What you might want to do is have your dyno operator print you a graph out that is uncorrected as well as a copy of those actual numbers corrected to SAE or STD numbers. Or you can get real close to those actual numbers by reducing them by the percentage factor above 1.0 they have been inflated by. Then you will see the effects of elevation you dyno at.
Your uncorrected numbers are the only true numbers your engine was able to produce based on it's state of tune for the conditions at time of that run. Actual Uncorrected numbers for conditions for that run down the long black dyno are what count to racers. Corrected numbers don't mean squat to them.

sorry this is all I have. Ill see if I can get corrected to please the H-T community lol. Either way the only way to see what power im really making is on the track. Dyno is for tuning purposes only

very true, but, uncorrected numbers read higher. and for me, a person that honestly knows how difficult it is to make a real 200whp out of a 1.8L, its misleading. i could have made about 204whp and 146wtq uncorrected.

That's never going to happen, There is no pleasing the H-T community. Nice setup you have going.
