Alright heres the deal im looking at buyin the vcm suite software but i was wandering if it was all that great and if it was user friendly.
I drive an 03 avalanche 5.3 with a 4l60e transmission
It currently has a cold air intake and exhaust on it and I am gonna put shorty headers and true duals and replace cats with high flows and remove second cats. Is it possible to remove both my dads friend has an exhaust shop he can make me a pipe with the bungs in it? And eventually get heads cam throttle body and intake.
So can i take the torque management off and make it bark tires and leave the line better and shift at 6k? If so is it hard to set up.
And also what kind of power gains would i be looking at?
Any help or advice would be greatly appreciated.
O yeah and fuel economy doesnt have to be great i only drive it in town and i need the power to get out into this crazy traffic and i take it to street car night at the drag strip.
