Car was running and shifting fine before install of TCI Super Street Fighter 3000 Stall 2.2:1 STR and ASP underdrive pulley. We have LS1 Edit and have lowered 2-3 shift point to 66 mph and raised 2nd rev limiter to 6300. At 60 mph hit it drops to 2nd then still hits rev limiter on 2-3 shift. How far do I have to take shift points or rev limiter?

 

Each car will react different, bumb up the rev, or lower your shift points.

 

just raise the rev limiter to 6600 and that shold be fine..if you program it and expect to run it at the track(which im sure) put in your tire hieght for your slicks not your street tires... on my street tires it bags the rev limiter but its perfect at the track!

 

I have this same converter and the 2-3 shift
is not a problem I've had. 66MPH is way low;
what's in that 12-bolt, for gears? With 3.23s
I have 81MPH / 6000RPM shift points. I'd set
the rev limiter for safety, the RPM shiftpoint
200RPM lower (300RPM for the 1-2) and start
nudging the MPH down until you stop hitting
the rev limit.
