[QUOTE="BanjoBoy, post: 1416106, member: 19829"] 1.) When I do a TBS, I sync the TBs at 4K rpm, (Trick I dun learned on the forum.) most shops just the the TBS at idle. But doubt this will help you any. 2.) The mechanic who stuck his finger in the tail pipe (KINKY!) is correct, these things run too lean off idle, and this is the problem. He's correct that that the G2 is a band-aide. As posted previously in this thread, I use a Dynojet Power Commander Fuel Controller, (PCFC) and it prolly ain't legal in Kalifornia. Now that I think about, think I do recall some places wouldn't sell it to me do to my location. 3.) The mechanic that said it wouldn't help below 4K IS TOTALLY INCORRECT!. In my picture there's 3 dials; 1 is for the 1st 3rd of the rpm range, the second is for the 2nd 3rd of the rpm range, and the 3rd for the 3rd of the rpm range. As you can see from my picture, I'm on "map1" the far left dial. I loaded a couple other maps, but don't use them, their "stock" map with some tweaks seems fine. There no Kalifornia Power Commanders, they're all the same. I'm a simple kinda guy, and the PCFC was cheap, and simple. I read about peeps who swear by the G2, but like your mechanic said, it's a band aide; it doesn't address the root cause which is lean fueling off idle. [/QUOTE]
