new tune, no MAF ? I recently received my MOT from a reputable tuner and I installed it correctly, but it wouldn't run hardly at all. Then I unplugged the MAF sensor and it runs and idles fine. Is it possible that I got a tune that was MAF delete? I've tried contacting the tuner several times over the past two weeks, and haven't received any response.

No it sounds like they did a bad job tuning the MAF itself. Without it, the car runs fine but with it it runs like ****.
A tune with a MAF delete like you mentioned won't make a difference whether the MAF is plugged in or not, as the MAF is actually deleted in the tune and the computer won't know if the MAF is plugged in or not...it just knows to ignore it.

I hate to think I got a bad tune from such a reputable tuner, though it sucks I can't get ahold of him. Any other ideas, bad MAF sensor, IAC, or TPS could be off? There are no codes at all and it runs fine, but I don't want to run it without the MAF sensor hooked up.
