hay guys im running a 5.7 tpi l98 stock... my fuel pump just went out so i got a 100 psi hi perf fuel pump, fuel sending unit and asembly, fuel regulator adj, and fuel filter... My question is that i want to replace my injectors too but dont want to buy 8 stock 21lb injecters because im going to do some serious mods in 6 months from now... i want to get 30lb... if i get 30lb injectors do i have to replace anything else i realy dont want to replace ecm... would it run ok on this old engine 190,00 miles... or would it be better to leave stock injectors... before the fuel pump went the car ran realy jerky so im thinking injectors too... any sugestions????
