Well i have a 98 LS with a skunk2 manifold, chipped and full exhaust...A friend of mines is trying to get rid of sum 270cc injectors that were on a blown b18c1 that he purchased.... my question is that if i get those injectors from my friend will they make a difference in my LS..performance wise?

 

^^

 

No. Absolutely not. You have nothing that would require more fuel than what your stock fuel system is capable of.

 

^^ To add to that, you have no method of correcting for the additional fuel. Putting those larger injectors in would make your car run like crap. In the end, you'd probably lose power....

 

o ook.. currently i have a fuel pressure regulator and its set at 39psi... and when i put the chip in the ecu it made a big difference and blows a big back fire as i switch to 2nd ..feels a little like boost lol

 

thats not good... probably wanna get rid of that chip and get some sort of real tunning
