Really high boost and no fuel cut...
Ok for some reason my car is running 19psi and taking it just fine... all the way to the redline. I have a 255 fuel pump without a FPR (previous owner is a d-bag) and thats all the fuel mods i have... no tune...
Anyone have an idea as to why that might be?

RE: Really high boost and no fuel cut...
NO fpr??? BAD idea you're gonna kill the injectors... But that's likely why no fuel cut. They're seeing MUCH more pressure than they should forcing more fuel out in the same amount of time that they would normally allow the right aamount out with... Yeah I just confused myself... Kinda like water... You open the garden hose valve just a little bit then when you go squeeze the trigger for say 10 seconds you oly get a little bit of water right? Now open the valve all the way squeeze for that same 10 seconds and you spray half way across the lawn... Make more sense now?
