Ok,,i just got my chip today,,im in san diego, ca.From what they told me, if you need a custom burn it was $125 on top of the $265 for the chip. Thats the price i was told at JBA here and superchip when i called them. THey do their own burns but they get the files from the main office in FL. Performance wise i have only noticed a little difference in power. My rev limiter is gone but i still govern at 115mph, they said they were gonna research that and would probably have top redo my chip. PM me if you wanna know the results. I dont know much about the diablo chip. I got the superchip from recommendations from fellow CEG'ers.
