no I have not yet had a tune I had a rocker stud break Thursday before last and so i had to pull one head to get it out which in turn led to alot of cash and some fancy new parts. I just got it back together last Friday night after waiting on parts and so on. Cranked right up ran great. Stopped by a few performance shops to see about a tune but no one could get to it due to the holiday weekend and just backed up with business. When I stopped at Atlanta Performance the guy hooked it laptop up to the truck and checked everything out says everything looks good. Same results at a shop up here in Memphis today, which led to thoughts on the valves. If I were home I'd run a compression test and a leak down but i'm not home and i don't have those wonderful tools with me. We tried the old school dollar test and i do have some suction in the exhaust, which would most likely be the exhaust valve allowing air to pull back through on the intake stroke yes? just really weird to have that " night and day " effect which is exactly what it is.

When I dropped the heads off to have the stud removed they cleaned them. Could that have removed deposits that were keepin the valves tight?
Let's keep an open mind here folks, I want her to make it home alive. I would love to just drop a 6 in it but not right after all the cash I've put in the past week.
