What do you think is the best available mail order tune out there? I'm going to put in a cc503 pretty soon here, and I'd like to only have mail in my PCM once. The car will be a DD, just looking for a tune to get the most out of this cam.

 

We've had awesome luck with madtuner.com, otherwise I've heard good things about pcmforless.com I'm sure either one will do you just fine. I had a 355 LT1 with GM847 cam (a bit wilder than a CC503) and the car ran perfect with the MadZ tune, no idle surging issues, just perfect driveability from day one.

 

yep another vote for madZ.. ive had 2 tunes by ian, and both where spot on. one was for a cc503 the other was for a GM847

 

where would I get a cc503 if I was interested in a cam for my 93Z

 

Summit racing. $288.95. Part number is CCA-07-503-8.

 

I've had nothing but good service from Ion AKA Mawolf @ madtuner.com. Been using him for at least 5-6 years.

I've been using Ion (MadZ) for 7 years and 5 tunes... When i get the the 355 back together he'll be tuning that too.....
