Actually, you have it just backwards. The stock intakes are too turbulent on the 3800'*. The maf screen actually makes the airflow more laminar so the sensor can determine how much air is coming in. When the idle is affected by it'* removal, the idle goes DOWN, cuz it leans the mixture out, thinking there'* less air. It can learn itself back, but really the only way to be able to remove it is a straight smooth walled or slightly bent custom intake and cone filter. Laminar enough flow to remove it.

I took off the MAF screen and it had better throttle response and overall better performance. It stills idels the same so I would segjest doing it.

I would like to try it, but I would need my dad'* help, and he would just wonder why the hell I would want to do that in the first place.

:( I to0k out the MAF screen the other day, while cleaning my intake, and I noticed that my car ran horribly!!! I drove around a while, just to see if it was just me, but the idle was so rough, the car killed several times. My car also wouldn't shift as well, it sorta hesitated from 1st to 2nd. After my "testing" was complete, I have found that the MAF screen works better installed, and did not help my intake breath any better. I was sorta dissapointed, hearing all of the go0d feedback of this idea.[ I have a CAI incase you were wondering]

There is one thing Timsmooth that you forgot, you have a 88 Bonneville. The computers in those are not even close to being adaptive. They are just designed to work w/ what the factory had. In order to do anything to the car, you have to retune it. It'* like all 80'* car'* they need retuning after every modification.

Well I can't find a chip for it, do you have any suggestions? I have heard of some kind of chip on eBay for my car from [email protected], but I m not sure if it is worth the money. I want to get a chip, but when I ask the techs at any of the chip companies web site, they never reply back, or don't carry one for my car.

You are pretty much out of luck. The only chip company that might have that old of a program would be Superchips. But the 88-91 Bonneville'* no one does anything for to be realistic because the engine is not worth it to work on and not a big enough market to develop products. Pretty much everything will be custom fabbed for your car, so if yu want to spend lots of money then go for it. I noticed on your website you want to put airbags, go for that and don't worry about performance.

The 88-91 computers do have some adatability just not as much as the newer ones. Any car that uses MAF technology instead of speed density technology can adapt somewhat.

I know mine has adapated to the open element intake I installed. I do have a computer that is about two years old though so that might have something to do with it.

The power difference of a maf screen is a waste of time in my mind because the amount of hp gain is way to small for the possible headache. If you are going to keep your engine then get the heads done. Then get a cam done. Now this will give you a bit more hp. when you are ready you can add better internals and swap in a centrifugal sc but this will cost more than if you did all this with a non sc series 2 swap. I personally believe the non sc series 2 is a great way to go because of the cheaper entry price and somewhat equal capability compared to a sc series 2. Well then there is the v8 option. Lots of choices.
