Time for mods ecu?

Im in the same boat as you. Im ready. Im in Long Island NY. I want a drive up shop. I dont wanna mail away my ECU.
No ECU flash will give you 565HP on its own. When you talk stage II you are doing more mods than that. Exhaust ect..
On another forum plus I called to ask it's 2500$ no more no less unless you getting headers then it's more

thanks for the info. BTW how many man hours does it take to get the intake gasket and thermostat installed? They seem wo be a must with that tune.
435RW by 20% is 543HP
435.68/.80=544.60 so i should of said 545HP from tune only

432.48 RWHP in 5th Gear on an independent dyno for less than $1500. Not too shabby!

Although I didn't get a Kleeman tune, ACG NY did my LSD install
about two weeks ago and I couldn't be happier.
