Hit me up on Instagram, @sam1el on there too. Happy to answer anything. I generally stay off here or fb because of the trolling and general douchebaggery.
long/short.... it's no different than tuning an auto in any way other than you don't need a trans build, you just need a clutch. about as much hand holding as I'm willing to give with that intro. everything else you've asked has been beaten to death on here, fb, discord, everywhere you can ask so..
