Do I want SP or should I keep the MAF?

Id rather delete the MAF if possible(one less thing to fail) in my 96 trans am 355/70mm turbo setup. What are the pros and cons of removing it?

Pros to remove: Like you said, one less thing to fail, although i haven't heard of many failing. Maybe get some part throttle surging depending on where you have it mounted on the pressure side. Cons: Trying to dial in a speed density tune. I'd probably leave it unless your having problems with it or the inside diameter of it is smaller then the i.d. of your pressure side intake tube to the throttle body and your looking to get rid of a restriction.

anyone else?

i would just keep it and tune around it....people have been to the 1000hp with the stock pcm with the MAF sensor still on the car.....

im not sure if its working properly or not. And I dont want to blow up my motor with the initial break in and find out it was the problem

I'd keep it. GM spent alot of time and money designing our MAF systems so the cars would get good gas mileage, low emissions and good driveability. Its easy to tune and doesn't really create much of a restriction if it is descreened which is a whole other issue. I descreened mine and still use the stock MAF tables with good success. Others will say you have to tune the MAF tables after descreening. My personal observation is that you have to be careful where you mount the MAF. Because if the airflow is not straight it will cause problems. If you put the MAF in the stock location you will be fine. I've tried speed density and felt the MAF gave me better driveability. But it is not a big difference. If your MAF is bad it will usually give you a code. Hope this helps.

How much of a restriction would you say the screen would be causing? I'd prefer to leave it on so that it could straighten out the airflow going over the sensor. I got a PTK Gen II kit and am wanting to move the MAF over to the pressure side for the drive-ability benefits.

+1 for keeping it. I have the stock descreeened MAF as well as the stock PCM on my 95 Z28, and am making 614 at the wheels just fine. Granted after a certain amount, the MAF will be maxed out, but a good tuner can tune around this.

The MAF will support up to about 500 rwhp before max'ing out. If you get rid of it, then the stock SD tune will only "see" 0 boost at full throttle, so it'll go very lean. You could do a 2 bar SD tune, but very very few (in fact maybe only 1) have successfully done this.
