Took mine out last night while I was working on my CAI. Ran like dog crap at idle. Drove it for awhile to try to teach it, to no avail. I've read failure and success stories on this, I'm one of the former. I'm wondering if it'* a factor of NA or SC? Maybe the guys with ported and polished intakes have better luck. Anyway, my CAI work taught me an important lesson. At least with the SC engines, you want an intake surface area at least 4X the original. This has always proved to be 2X on the NA intakes I've done in the last 10 years or so, but the SC really hungers for the flow. I'm burying the Boost needle now, with no pulley change. Good thing, 'cuz I can't find a smaller Series I pulley anywhere.
Anybody had any similar experiences with MAF or CAI
