Buying a Fast Toys 98mm lid and 85mm MAF this evening. I will be able to delete the AIR system and make the block off plates and put them on myself, easy enough. However, the car is a 2000 Trans Am. I have read that I will need a new pigtail for the different MAF. Is this true?

Also I have a Flowmaster Catback on the car. Should I go ahead and do this mod then send Frost my PCM and let him tune it for the lid, maf, and catback?

Appreciate the advice!

P.S. - In the future I plan on installing the LS6 intake and removing the EGR.

The maf will require a tune. I would do it all at once then the tune. Biggest gain for you now would be long tubes

Right on. Thank you.
Im getting an SLP 85mm MAF and I read they're not too bad untuned. Just run lean. Differs from car to car.

Also I've read a lot about the SLP MAF being overpriced and overrated. However it's the MAF I got with the 98mm FT lid. Will it be okay to run without a tune until i can get an HP tuner or a frost tune?

Running the larger MAF without a tune is usually not an good idea. Your maf tables will be off by quite a bit. It can cause the car to run lean on a stock tune.

Right. That's what I was thinking, but I read somewhere that the SLP 85mm MAF has the sensor in it to mock a stock MAF table.

Just unplug the MAF until you get to the tuners. Car will run in SD mode, which will be fine. Then, no lean running issues, and you don't screw up your fuel trims.
