Stock stingers do 12.9-13.1, A Jb4 on map2 should run 12.5ish if not quicker. that half second is a large difference. Add Meth or e30 and a stinger can break 11s with the JB4.i just watched a drag race with two mod'd stingers and they only got 12's.
stock stingers get 12's. its the thread about 1/4 mile races.
I just got a 22 GT1 and would like to get the JB4, is it worth it w/o any other mods, like exhaust or intake, etc...?? or does it work better with combined mods?
It's the most reliable piggyback tune. No issues. It has alot of safety features aswell.Thanks for the post. I also want to add a Jb4 for my 2022 GT2, but have been hesitant.
Is there any threads on here of long term reviews with Jb4?
I’d probably just stay on map1It's the most reliable piggyback tune. No issues. It has alot of safety features aswell.
I'm in LA, running map 2 on 91 no sweat. Mix in some E85 and I daily map 3.I’d probably just stay on map1
I live in LA and we don’t even have 93 octane. I would have to do a mix of 101 and 91.
