Max Boost to Max MAF or PCM I want to do FI on my '02 TA, but I want to know high of boost could I run on this car before I max out the MAF or MAP sensors. I have HP Tuner for the tuning portion, but I don't want to do the SD tuning on this car. I know there are a few of you out there that has maxed out their sensors, I would like to hear from them. BTW, I do have an SLP 85mm MAF available too, would that help.

It' going to vary for each setup and it's important to remember that boost is just a messure of the restriction of the air flow, not actual airflow which is what the MAF/PCM limit is all about.
It's probably safe to say it will happen between 15-17lbs on most stock PCM/MAF combos.

So I thought it would be best to offer a range so someone doesn't count their chickens before they're hatched.

I should point out that my pegging the MAF/PCM limits is after every scaling trick in the book.
So I'm assuming that people are trying their best to stretch the computer limits of 511 grams/sec using those tricks. In my efforts with my tuner's help we managed to get it to 17lbs and we would peg the MAF at 4800-5000 rpms at that level. At 16lbs the car was fine.

I remembering reading about guys that use the MAFT-Pro to ditch the MAF sensor completely and the MAFT-Pro to the PCM to adjust fuel and spark from a wideband oxygen sensor. How does this affect daily driving and fuel economy. I know that I won't what the car was rated for, but I don't want a hugh impact with cruising on the highway or light throttle accelerations.

Like any other tuning tool, you can dial in your dailly cruising as lean as you want to in order to maintain fuel economy. The trade off is how safe do you want to be as you transition to WOT? It's not the best idea in the world to go from a lean spot into a high demand fuel situation in WOT.
