What can the handheld do?

[trailmix]

Can i modify directly from the device? or do i need a custom tune right away? my truck is currently n/a,but would like to tweak it a bit till i finish the turbo motor

Thanx,Donny

uhhhhhhhhh..... lol just leave the truck alone til the motor swap is done, then pay a professional who know how to tune it correctly to get your ecu set straight for the turbo motor.

you will still need someone who knows how to tune it write a tune.. or buy the $300 software and learn it on your own

There are things you can change with just the tuner, but mostly just global spark. If you want to tune that much, wait, or get someone to do it that has the software like Low said.
