I just installed my miller MAF with 19lb injector chip, I went to start the car and it instantly got a CEL, the car is idling okay(occasional up and down ) but 95% of the time the idle is fine, I went to go drive it and the CEL is still on, the car was hesitant at about 3/4 throttle, but perfectly fine at WOT. I drove about 20miles and the check engine light didn't try to go off even once, the car feels like it has plenty of power, and it sounds AMAZING:)I came home and did a stomp test and got 1215 which Air mass/volume sensor. I revved it in the driveway to about 3k and it had an intake backfire, I revved it again and it didn't. Could this be a TPS issue or something? the car drives great at WOT.

did you get the new miller maf? if so I think you might actually one of the first. I woudl call miller. -
That's not good. I have an intermittent WOT problem and my AFM has been messed with, so I was hoping I could just get the Miller MAF and kill 2 birds with one stone.
Let us know if you figure out what's going on.

FIXED no more CEL, all I did was spin it so the plug is now under the ICV and now the car drives amazing, throttle response is amazing, it idles super smooth, pulls really hard, and mid range power feels great, now it shifts right into the next power band and keeps going and going. This is a great upgrade and is only $100 more than a Mark D chip. The sound the car makes with this maf is great, the car used to take a big gulp of air and then go, but now the induction noise lasts all the way 6000rpms. Makes the car drive so much better than an AFM. I dont know how much more power the car got, but it basically feels like the bump you get from a chip, and now my bottom end hesitation is also gone.
for $299 you get the miller chip for either stock injectors or 19lb injectors and a brand new Bosh plug and play MAF.

I was looking in to getting one of these. Any other improvements you notice with it?PNW CREW

the improvements I've noticed are, super smooth idle, more powerful midrange, my bottom end hesitation is gone, sound, and it weighs basically nothing.
basically it gets rid of all problems the AFM causes and it gives a more noticeable gain than a performance chip. Why spend $229 on a performance chip when you can spend $70(+shipping) more and get rid of the AFM forever and get a chip for either 19lb injectors or stock injectors.
