[QUOTE="fishpick, post: 15603552, member: 182347"] Good info. That's something I'll log with the new tune. There's so many parameters to log... glad I have the best dude out there on my car! But I also know for SURE I have belt slip now. It's not even a question at this point. Finally got rid of my exhaust that the blower made drone like a hive of 3500# bees and put on FRPP Tourings and am infinitely happier... AND that now let's me clearly hear a sound in the 3000-3500 range that's kinda like the whistle a steam valve letoff might make... when that sound happens I can watch my boost gauge drop to 5-ish... if I then feather off the accelerator and then back into it more gently the boost goes to 9-ish (if it does NOT make that sound) and the car pulls super strong. This sound is not the SC whine - it's not even close to it. And while this happens you can now also audibly hear the SC whine "be less" when the "whistle / squeal" happens... The idlers are covered in a tan and black dust. And the cutouts in the Whipple pulley have dust in them after a short ride of making the car make that "whistle/squeal" 4-5 times. Totally the belt. No doubt. Not saying the canned tune doesn't also have issues (I'm sure it does) but I gotta get the mechanical figured out before the software! I have my tensioner at 80%. So my next steps were to remove the belt, turn it inside out, and look for glazing. None. I then cleansed all the ribbed pulleys with brake cleaner and pipe cleaners to get any and all possible lubricants off them (not that there were any, just ruling that out) and got a bit of black dust out of the grooves as well. Today I'm going to flip the direction of belt travel and see if that changes things. And I have a 7/8" shorter belt arriving from Amazon today to try as well... (assuming the weather holds until after Mothers Day brunch) Been talking with Whipple too - many of these suggestions were theirs. Something's gotta work... (other than "get a 10 rib setup") Sent from my iPhone using the [url=http://r.tapatalk.com/byo?rid=92568]svtperformance.com mobile app[/url] [/QUOTE]
