But, i did have the SI trim and 9psi pulley so it was pushing more air at idle. You should be able to trim down any of the springs to get the tension right.

OK....have it at the softest setting and it's still closed. How far open does it need to be? Do u think this is the reason I am.getting high Idle? We ran a smoker and couldn't find any vacuum leaks. Tried doing a Idle Learning via EcuTek but the tests failed and made my idle worse. Now idling at 1400-1500 RPM.
Weird thing is this just started happening. When I first cranked the car my idle was where it should be.....high 700s low 800s (RPM). Thinking it may be the Throttle Chambers but I'm not getting any codes for that.
