As most of you know, ive had problems with number 7 piston. I did the vic jr intake with vette filter and speedinc rails. It pulls alot harder and has good a/f. Well i finally got my fuel pressure gauge and it seems at wot it will drop to around 48 then go back up when it shifts. I have stock intake and a walbro inline. I just ordered a racetronics intank pump for 98 camaro and the wire harness kit.

 

what are your afr's when the pressure drops?

 

11.4-11.7
