so when i turn my key and the fuel pump engages it reads 43 and then when i start it, it idles at 40. i know its supposed to be 48-55, then a 3-10psi drop at idle. is this enough to mess things up? i am having issues when hittin the gas goin up a hill or just tryin to get on it. ive narrowed it down to preatty much a cat or low fuel pressure. what should i do first? maybe get a voltage booster and hi flow fuel filter first? then just eliminate the cat and get an emulator?
