HHmm. I did the muffler delete yesterday and my 1/4 times suffered today. Seems like it needed to launch at higher rpms for the car to actually lower my 60' times. And my 1/4 trap speeds were lower by almost 2-3 mph.
Pre MD I would launch at 1500rpm and today I had to launch around 2krpm. Any thoughts?
