MAF.....good or bad??? I have a SLP 85mm MAF.....that I have not installed.
Someone told me down here in the Austin Texas area, that its a bad idea....something to do with weather conditions and running rich or lean.
Can someone elaborate on this subject please.
I do not have the MAFT...do I have to have it?
Current mods if it matters are listed in sig.
Thanks,
Chris.

Re: MAF.....good or bad??? Also...since it is so easy to install....Will I be able to switch between the two at the track? For instance run a few with the stock MAF....then switch at the track to the 85mm, to see if there is a positive or negative difference????
Or is this one of those situations where you have to drive the car 50-100 miles for the computer to 'learn' the change?

Re: MAF.....good or bad??? Since you asked so nicely. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
I don't have any personal experience with SLP's 85mm MAF. BUT, there are plenty of guys here that run 10's and 11's on the stock MAF. IMO, you're better off using the mod money somewhere else. You should give it a shot though since you already have it. Swapping them out at the track may not give accurate results. I believe the computer will have to re-learn everything.

Re: MAF.....good or bad??? There is a general consenses that the SLP 85mm is more bad than good, although i take everything with a grain of salt (if you know what you are doing you can make anything work). You definately will need some sort of tuning device (maft or hypertech or one of the tuning programs) to get it right, or drive on it for a long time. If you do a search you can find some info. I am also interested in getting one eventually, here is a link to a previous discussion:

You wont be able to switch out the MAFs easily in that the computer will be set up for one or the other and changing it without reprogramming will screw you A/F and possibly your timing. For what it is worth the semptember issue of Gm HighTech Performance tested one and reported 5 hp gain. But they had a tune and drove it for 500 miles, they also had the smooth bellows too.

Re: MAF.....good or bad??? Here's another one from another section.

Do you have access to ATAP or scanner of any kind? If you do, you could check and see what your a/f is before and after. Then check again after 150 miles or so. From what I understand your PCM will eventually "learn" the new airlow and adjust accordingly. Every car does respond differently to these. To use it you may end up having to use a MAFT. And no, you can't just swap it (and the stock one back and forth) at the track. Good luck.
