[QUOTE="PSUCOBRA96, post: 11505647, member: 54826"] sorry I have been missing for a bit: No cats no sai all turned of in the tune. NO IMRC- they have been turned off and the timing bumped to accommodate Fuel pressure has not been checked, maybe one of the injectors is getting clogged. Whats the best way to check fuel pressure? I feel like a noob today. I haven't checked for vacuum leaks, but could be it is only really bad at the higher rpms. I will put that on my list as maybe one of the seals on the valve covers are not sealing right. Could be a tune problem though, I remember I ran both tunes street and strip and had little difference that night. Could have been an off night but I just don't think so, everyone else was running faster that night. Interesting idea workman, not sure I have no clue on that kinda stuff. See my main concern is I have C-heads waiting to go on and I am in a debate as to get them on or see if I can diagnose the problem first if there is one. If I do the C-heads I will be getting a new tune so that will tell me if I am having issues I guess. I would just prefer to look at all factors beforehand to attempt a good outcome in the end. I hate changing stuff when things could be wrong. Some of the other changes I am making this year/have made is I will be running skinnys and some serious tire plus just have 4.30s and the rear all built up. So if the car gets slower I may be peeved. So many damn things to investigate now [/QUOTE]
