I have jb4 auto tune =map 5 dci and catback exhaust automatic with paddle shifters

I want to know do I brake boost? launch in first or second any methods?

thank you
From my experience DSC off, Map 5, brake boost at 2.5k rpm, launch in 2nd with a kickdown blocker or else it will auto downshift and mess you up, shift around 6200rpm. Do not run DS mode unless you are trying to get a slower time. Ask me how I know. lol

What track are you planning to take your car?

you should go to auto club speed way they have a 1/4 mile track there. its pretty fun and really well priced. i paid 20 dollars and did about 7 passes. i have also gone to qualcomm but didnt really like the track, horrible trying to hook up. barona raceway was good but most of the cars that race there arent even street legal so you might feel kinda slow if your not running in the 6's (1/8 mile).

all in all have fun and maybe ill see you out one of these nights.
