You need a catless tune !
And I Personally never ever run from 1st nor 2nd I always start in 3rd at 5k rpm
even then I get wheel spin , also get a little wheel spIn going into 4th & all this is on 295 rears .
These car wake up above 110 to 200 mph shit gets hairy !! Dct has so much advantage from 1st - 4th kinda wish I got a dct ....
