I have to do this to the Vett! I am still running the stock tune (Not good!) That engine has so much left on the Plate that only a Tunner can get out of it. Plus I am gonna have to do it to my Wifes New to Us Hemi Jeep Commander project. We bought it with a Blown engine, Its at the Machine shop now being machined, I am doing all kinds of mods to the engine taking it from a 5.7 to a 6.1 Bore with a cam, Eagle heads and Intake and a set of long tube headers. After the Tune is done we are planning A 4 inch lift with 33-35 inch tires and Gears. Its not for me! She wants the BIG Truck! That Growls! lol
If They were Carbs I wouldn't have a problem getting it really close doing it myself, but this dang Electronic fuel injection and computers has me at the Mercy of the Dyno tuners!
I have estimates from $500 to $1500 for the Vett and the same for the Jeep.
You cant beat Dyno tuning though, Its not just for electronic fuel injection! They have all the cool tools to use, they can see what works & what doesn't in real time with the car pulling a Load right there next to a tool box its the way to go even with a Carb!
