The strange thing is that I did not have any of these problems until the day I installed the Procharger.

What is this and what am I looking at spending? Is it really necessary?

i Prefer speed density on boosted cars... they seem to run ALOT better.. PM me if u wanna talk about a few things.

thats what i kinda figured at idle it has no boost with the blower spinning slowly so the MAS should see vac unless you got the blower over driven like 26000 to 1 to max out the MAS lol just visualize it its like a 20inch rim to a lug nut 0 0 haha i found it found it funny

i know alot of guys around my area here the have some NASTY FI cars that are still MAS tuned not SD now granted SD is an awesome thing they say but wouldnt you rather see the air coming into the motor in real time not just estimated like the other thread said? i dont really know that much about SD but it seems like MAS is not that bad as long as you have the stock split MAS housing then tuning is easy even with HP tuners or LiveLink or a dyno tune

Hard to say without seeing the car but in the last year we've found 10 bad MAF's.They seem to read fine but majorly lean out at WOT. BUT it could easilly be the tuning too.

That is strange, could be the tune though. You're pushing in a lot more air so if fuel isn't up to par then you'd have an issue. I'd try switching MAF's w/a buddy and see what happens. It could have just been coincidence, or maybe somehow oil from the blower/PCV got on the MAF and screwed it up.

Necessary, no, ideal though. I'm going 3 Bar SD, no more guessing for the computer.

I read that the 98 MAFs are a little more finicky when it comes to boost due to the different PCM.

I used to get that code on my 98 when I reved the car out with a cam only package ,up abouve 6k . I heard that its common with the 98's . I am sure the procharge will max that maf out . You need to fix it in the tune though .

But if your getting it that code at idle somethings wrong

The trouble code does not appear until 5,800 r.p.m.'s and the idle still goes up and down.

The car was not tuned yet. All he did was set up the injectors and richened up the A/F

If you have a friend with a good MAF, borrow theirs to see how the car acts w/ it.

DO NOT beat on the car until it is tuned.

X4 Find a good tuner Frank96SS Knows what he's doing. you wont regret the move to SD. MAF's are for fords

Serious though I would recommend a good 2 bar SD tune. You will be happy with the results.

I definnitly am not trying to beat on it. The A/F is around 14.7:1 whenever there is a load on the engine. At WOT, the A/F goes to 10.5:1 and it is only at 16:1 when idling. The tuner has it set up this way to be safe until I figure out the problem

Well its not going to be safe with a maf fault. If it sets the 103 under the right condition it could revert to the ve table and use the map. This would be bad causing you to go lean with the the stock 1 bar setup you have right now.
