Look at the thread in my Sig. Yes i am an enigneer that works on alternative fuel engines, i tested the intercooler before and after and found no change in it's cooling abilities.

and believe me a dyno isn't teh best way to measure performance on such a detailed level unless it;s in a completely controleld enviroment (ambient air temp, humidity, barometric pressure) the correction factors on Dyno's will change dramatically depending on where the sensors are placed.

i knew of a shop placed the sensors in the Water heater closet but ran the cars in an open bay, when the computer "corrected" the numbers to STD it would alwyas be higher. becaue it though it was 90+ degrees and humid no matter what.
