No, but the fuel pump has also given me no reason to think it's bad. I'm not sure what XLRV was expecting me to do - walk into my mechanic or the dealer and say hey I got this custom tune for my car and when it's turned on the engine makes a funny noise! I would've been laughed out of the shop imo.
THAT'S WHAT YOU GET WHEN YOU LET AMATEURS MOD YOUR CAR, they might say. And they would be partially right.
When I got a tune from ILLS for my first LS, I had some issues that he tweaked for me afterwards. Was very good service, he adjusted the tranny shifting for me as well, and sent me new tune files.
This one, got the tune, was still snowing out so I didn't install it right away (first put it on about a month after ILLS sent it to me), noticed within the first week this noise (wasn't driving it hard) and proceeded to contact ILLS thru e-mail, phone calls, PM (all over time) and never got a response (and we now know why that was - XLRV was talking smack suggesting I bothered ILLS too much - rofl).
So I don't think I'm wrong in thinking something is probably incorrect with the tune and needs adjusting, but I never got any chance for that so who knows.
Some on this forum seemed to think I should have started replacing all kinds of parts, but I think most sane people will agree I was following the right path to figure out the issue by talking to the guy who configured it for starters, and going from there. At the time my car was a baby - 3 1/2 years old and only 28k miles.
I'm going to get a new tune from Torrie before spring next year. Then I will find out if I am wrong and if my car has a more serious problem. If so I'll be sure to let XLRV know.
