i accidentalyy orderd a 305 tune from pcmforless and i have a 503 cam if any one has a file to help it would be great i use tunercat thanks

 

Why dont you ask bryan to change it should have free updates if you e-mail ordered it for 6 months

 

yeah but its another 25 bucks if you change cams i didnt do that but im not sure if he would ill email him and ask

 

I would run it, the cams are so close and if you have a 94/95 PCM I doubt there is much difference at all. I have done loads of tunes for both cams in C4 Corvettes and F bodys. The 94/95 cars using a MAF strategy are very forgiving, take the $25 and buy yourself a nice steak!
