Well I was thinking yours was the one that was claimed to have a couple pounds more boost than stock? Am I maybe thinking of the 227hp one below then?
Here's the two I was going off mostly:
evo 8: 271 rated - 212awhp = 21.77% loss
evo 9: 286 rated - 227awhp = 20.63% loss
also the t25 gsx only pulled off a 149, although it's old enough that it may need some work to be as good as stock.
