Has anyone sent out their computer module for a upgrade.
I have seen several vendors that say if you send them your module they will replace the chip and send it back to you.
Anyone done this, and was there any noticable improvement in performance of fuel economy?
Always sceptical of there promises from the aftermarket.
Thanks in advance.
