imagine having a turbo flow alot of air into the motor and not enough fuel... kaboom
there a car running say 5 psi with horrible or non existant tuning, would be less reliable than a 8-10 psi tuned motor...
How much would a good tuning help if i was upgrading to cold air intake from a stock intake? And how much would a good tune up help with just the stock intake? And how do I tune my engine? Thanks
Edit: All of the above is with no F/I
