Hey dish, not to say I told you so.....but that's exactly one of the things I told you to look for 3 weeks ago (page 10, post #1590) Glad you got it figured out though. What did they do, just remove the rest of the silicone and rebuild it without any ramping? I ask because that is what I did, and the engine still isn't right. Could be just way off tune now that the primary flow has changed. LMK, thanks!
