Re: Injector's 19lb vs 22lb

Hey I'm no tuner but I believe if you use the 22's instead of the 19's you need to have a chip burnt to change the injector constant. Then I would start with stock pressure (42PSI I think) and go from there. If you want to try it without changing the program, then I would go with less pressure to start with. I think you'll have problems though.
