is it true that if you only run 4.4 psi you dont need a tune?

 

i wouldn't

 

I wouldn't think so since you're not really forcing in enough air to totally through off the ecu, but with these modern cars you just never know.

 

i would just say it's not worth messing with a turbo and all of the costs and hassle involved for such a small amount of boost. i'd also say that if you're gonna turbo it you might as well tune it since you can handle like 3x that on a stock motor no problem

 

you might not have to, but even with the smallest thing like that i would, id rather be safe then sorry, even though i dont think such a small amoun to boost is worth it, id be running around 14

 

i am starting off at that for now until i can upgrade the fuel system which wont happen until i sell my third car to my bro

 

unless, would used fuel injectors and fuel pump be good or no? the guy said there are about 15000 mile on them
