I have been chasing this problem for a while now.My car seems to lose its pull when it gets into third and bucks a little.My 1/4 mile times have been real slow and 1/8 so so.My last 1/4 mile run was 11.69 @ 113 and my best 1/8 yesterday was 7.32@92.4. I think even my 1/8 mph should be higher with that et.I was running 24# and 29/27* timing in my extender extreme setup.My 60' was a best ever 1.60.The problem is when the car gets into third just before the 1/8 it stops pulling as good.I don't think it is trans slip.The heads are champion irons and have only 10,000 or less miles.Could valvesprings cause this?I have no KR at all on the scanmaster FP is set at 43# line off.I run the chip in open loop mode so the o2 sensor is out.What all should I check?
