I saved the tune to the diablo sport and try to connect to PC all i get is XModem timed out. and where could i download a custom tune for my truck i have headers, tb. spacer, mass air, and Diablo Sport. This is in a Wrecker that runs hard and long hours, but still has to haul ass to where your going please help.

Not sure about the timeout as it could be several things like COM port settings or baud rate settings.
As for a custom tune you should contact one of our CMR dealers for tuning info.
Not sure what MAF you have in there, but the stocker is a great piece.

Thanks

Give us a call at the office, we'll try to get it squared away.
Most aftermarket MAFs tend to lean out the MAF curve, then once you use the Predator to lean out the fuel curve, you may end up with some issues, so the stock MAF is always best.
