I have a few different 503 tunes I've been running, some modified by me and the others from Solomon. The one I'm currently running (my own edit) is fine when it warms up but the cam surge under 2k can get a little violent at parking lot speed. The ones Solomon sent me weren't nearly as good. I'd be willing to send some tunes in exchange for a good 503 bin.

Yeah, the best tune I have is actually a hybrid of a stock 95 M6 and SexyTransAm's tune (503, A4) from the depository. It's decent and I've been running it for about 10k but the cam surge gets a little violent with low rpm and speed (slow turns and parking lots). The other ones are from Solomon and were so off that I was afraid to drive my car around the block with it loaded. I gonna have him look at some logs but my friend lost my cable back during fall cruise week. I'm still waiting on a replacement.
We have a sponsor that does tuning as well...

talk to nate @sweet-94z28, awesome to work with, will go round and round with you until YOU feel its right. i have nothing but good things to say about his tunes. and his response times are awesome, i wanted to apologize to his fiance since he was doing tunes for me on her birthday lol
Let me know if you want some help with this. I've done quite a few cc503 cars. Cam surge is commonly caused by wide swings in timing. If you can control the timing corrections, you can usually smooth out the surge.
My name is Nate, does that mean I can help too :DQuote:

Nothing but good to say about Nate....even if you want to figure it out on your own he will help yeah out. Talked to him quite a bit since I went from LT1 Edit to Jet DST (CATS) and he was quite fast in responding to my questions. Did get closed loop dialed in as good as it is gonna get, but ended up locking into Open loop and got it to where I wanted it. Wish they had a table that you could command a certain A/F ratio for close loop. But that is in the LSx ecms I see from my 04 Silverado SS.
