Never had 2step/anti lag. had a 50 shot (wet) 1st/ half way through 2nd. getting up on the converter was not bad at all. actually launched like a bat outta hell!
I have my kit made up for my 2J , Not sure if im gonna use it, thinking about keeping the r154 in her to enjoy cruising more.
One thing i didnt like about the gm setup is cruising around . just not as fun as 5sp.
But im currently looking to make a 4L80e kit . I have my th350/2j setup for sale now.
