[QUOTE="01yellercobra, post: 16442662, member: 35549"] The lower fitting is notorious for causing issues in 03/04's. The elbow goes bad and causes a big vacuum leak. Personally I wouldn't want the engine to die as soon as the IAC is unplugged. What happens if the IAC goes bad and you're no where near home? Plus if you set the duty cycle where it should be (around 30%) the throttle blade will be opened a tad. From what I've see the smoke test is the best way to go. As for the MAF, it really depends on how close you are to pegging the 80mm. If you have some head room the 90mm really isn't necessary. But I can't see you having much room even with a low boost set up. [/QUOTE]
