thanks for all the info everyone.
I ordered a BAMA tuner last night for $400 with PATS pre-disabled (they can code it to turn off PATS in their shop before they ship it). I am not going to buy an ECM because it may not need one- a tune may take care of it if something through it out of whack. If I do, I will most certainly find a used one for about $100 and re-tune. Its worth a shot...the BAMA tuner will hold up to 10 tunes.
