Fuel pump and tuning question
So I got tuned on a bad pump a few months ago, i ran out of fuel at about 7500rpms. I just put a new pump in and the car bogs past 4500rpms. Am i gettting too much fuel now? before my exhaust would backfire on the old pump, now i get no backfire. Im sure i need a new tune but for the mean time could i turn the fuel pressure down? will that help at all? would the new fuel pump working more effeciently cause me to run rich? I have AEM EMS and an AEM FPR. thanks in advance

How is it going Jesus? 
You need an AFR gauge on the car to really tell whats going on. I'd invest in one as they are actually pretty cheap. (200-300)

Hey kevin, everything is going great. Car will be pretty close to done by next spring. I just want to break 400 on my CTSC. Yeah I will eventually pick one up. I'm sure my tune has changed because of the good fuel pump. Even my exhaust tone has changed a little bit. It's not as raspy and it doesn't pop. I will hopefully get tuned this weekend or next. I am really busy with work and school.
