k i recently traded my srt-4 in on an 05 evo 8. im havein a hard time finding some answers so i figured id ask the ppl who know. what is the stock boost psi??? and how far can i push the boost on a stock setup? only mods i have is an CAI and exhaust. any knowledge shared would be greatly appreciated ty for help l8r

 

stock is 19, on 91 octane 20 is about it, but on 93 octane you can do 22 pretty safe. with that intake you need to tune. the best thing for you would be getting a walbro fuel pump, mbc, and a flash. check out dynoflash.com

 

thanks man i kinda figured i would need a fuel pump. and thats all u can do to the stock turbo is 1-3 pounds more?

 

Exactly.
