Little update, the kid found me on facebook at 1am this morning. Not sure whats done to his still, but he seems like a nice guy. Said it was recently dyno tuned and did 310whp and 360wtq, and when I told him my mods, he basically said "no way that's it, how come I cant keep up with you?" Even though he even pointed out, "those huge cars are only 365 crank stock, WTH??"
Im not sure what a stock STi dynoes, but ill look more into it later.
I found a thread where a guy has been doing step by step dyno results for his 2012 Sti, so the kid I raced must have more done than this guy if hes really 320hp/360tq
