Nice. Seems a lil low bra. What was your afr? What size injectors ya using? Just a thought.

 

[OstarMotorsport]

does it? i mean it is just a 3071 not a 3076 and only has a 53.1mm inducer. with another couple of psi it would have done 450whp which is probably max psi on that turbo before it loses efficiency. Not to mention stock compression is 7.8:1

afr's 11.8 and 780cc injectors
