I have a 1994 Z28 with M6 and 150,000 Miles that I have only had for 3 months . It runs great after a new opt-spark, coil, water pump, wires, plugs, 24 lb SVO injectors, intake gasket, LT4 knock sensor and descreening of the MAF meter. Like I said the car runs great just dose not have the bottom end I was hoping. I only run 93 octane and was wondering if a tune by someone like pcmforless would help?

 

yes becuse the svo injectors are rated at a lower psi, and when you put them in our car they are acctually a bit bigger than 24 becuase of the higher fuel pressure. that doesnt sound like a whole lot but when your talking about a injector thats pulse widths are measure in milli seconds. thats alot.

and put the screen back in becuse it helps straight the air flow in the maf for a more accurate mesurement.
