Hey guys, new to the site. I just bought an 07 F-150 Harley last night, it has a whipple supercharger. I got the truck home last night and I found a PRO-CAL calibration flash tool in my console and I didn't know if the previous owner had already used it so I tryed to use it but it wouldn't download, I got an error code that said "General software download error" so I left it at that. today I came out to start the truck and now it won't start, dosen't even turn over. If anybody can help me figure out whats wrong?? it would be greatly appreciated.

 

did your computer have the pro-cal software?

 

bet you bottom dollar he already programmed the truck when he first got it done....why didnt you ask the previous owner? and do yourself a favor and call Justin Starkey at VMPtuning.com and get some programming thats not pig rich and crappy.
