I spent around 200 for my original chip.
I have spent around 1200.00 on custom burnt chips.
By the way this is on a LT1 camaro with heads, intake, cam, headers, 52 mm TB, Free flowing exhaust
through a flowmaster cat back, street/strip tranny, gears, fireball ignition, you name I've got it or had it on it (except for NOS or forced induction I like a NA car).
But my car will not run without a custom chip. I have real good luck with the private sector (not large corporations) on my latest chip, and they WILL give you a warranty on it unlike jet or hypertech.
