SO what if i had a custom tune for a gen3 with stock injectors and 3.4 pulley
I was running a 3" DP and 2.5" cat back w/Fender wall intake

Since then I got togs and will do a gen5 swap

Say my stock injectors lean out, will putting 42# ones in make any difference? will they pick up automaticly where the stock ones left off?

Would it hurt to blindly install them at the time of the gen5 install

Thanks guys
