2 years ago i had a 727 with a tight 4500 flash convertor
Car went my signature. 11.26
Last year i yanked out the 727, put in a Cope built 904, and had PTC build me a convertor
Best was 11.33..... convertor flashes 5200, right about what i figured was optimal. But i figure 14% slip now
With 727 best 60 foot was 1.62
With 904 best 60 was 1.53
The car did need rewired, lots of questionable stuff going on
Now its all new and up to date with zero issues
Maybe it was electrical related and getting worse, but the car was super consistent,went 6 rounds with it several times. So who knows
