My car has been tuned in SD for a while now and I've never been able to control my timing. This past weekend I found a new problem that never arises in 1/8th mile racing which is usually what I do. But this past weekend, I found the timing drops 8-9* about halfway through 3rd gear and the car is a dog on the big end of the track. There is no KR or any obvious signs for the car to do this. Back in February I ran quarter mile and it never did this. Any help is appreciated.
