Custom Tunes
Ken, What kind of things can I change when you have a chip custom tuned. I have a 2000 5.4L F-250, computer code CPY4. I need the custom tune for my JBA Headers I have installed. Can you tune the chip for a certain rpm range, ie(1000-4000) to get more low and mid range torque and power. I would also like to correct my spedo for 315/75/16 tires, firm up the tranny, and get rid of the speed limiter, So is this asking to much or is this do-able. Thanks TONY

Here's a list of what we program for (plus just about anything else):

The chip is programmed for power at all RPMs and throttle positions, not just the low end/mid-range. Correcting the speedometer is not a problem, I've handled the CPYx family of code many times.
Are the headers shorty or long tube?
