got a stock 90 ls teg except for cold air and exhaust...lets say i put a drag gen 2 kit on, and rebuild my 130K engine, how much HP and torque should I expect. Oh ya, add dyno tuning to that. By the way, how often, if ever, do you have to go back and dyno tune?

 

First of all ur not giving sufficient info. What boost are you gonna run????? When you say rebuild, what pistons comp?????? Stock or aftermarket??? What size injectors are u gonna use???? What EM are u gonna use??? these are things needed to know to make a somewhat accurate assumption as to your HP
