Need help with 99 GT.

[PeaRidgeBoy]

I've owned a few foxes and a couple 94-95 GT's, but I recently bought a 99 GT and I know nothing about these motors. As far as I can tell so far, this car has a stainless Bassani X-pipe, and catback. It also has a 77 Pro M mass air, and some kind of Steeda springs. What are the usual bolt ons and basics on these cars? I'm thinking about some 4.10's. I would like some advice though.

remove the pro-m it's only hurting your car. get the stock one.

4.10's - recomended

not saying you're wrong, just wondering why the pro m is hurting it? What is better about the stock one?

that's what the car is tuned for

Put the stock intake back on, do not forget to reset the PCM when you do so.

Before taking anyones advice on taking the pro-m off make sure you don't already have chip or flash tune with the pro-m's transfer curve programed into it. If so the pro-m is about the best of the aftermarket MAF's and probably isn't hurting you any. If it hasn't been tuned for the pro-m, the stock MAF will work better.

On a side note, you wouldn't happen to be from Pea Ridge, FL would you?

I'll look into it, thanks. Not FL, I'm from Alabama.

Usually boltons underdrives, gears, shifter, chassis stuff. Then more power choice your weapon n20, blower, turbo, N/A setup.
I'm wondering why you dislike the pro-m Tom has been my exp. that the pro-m's are the best.

 

[Stangboy017]

because the car isn't tuned for an MAF that size, it'll tend to lean out if you dont have it tuned for the larger MAF

 

[tomustang]

i doubt people go out and just add an MAF and have the car tuned to it. most people just buy the MAF and disregard the fact that is needs to be tuned/setup correctly.

that and the fact that the stocker maf is good up to 350-400hp give or take. theres no real need for it in a n/a stock non force induction application

When you guys talk about a N/A setup, are there any after market heads for this motor, or what all are you talking about?

I know this is not a direct answer, but this thread is pretty informative.

All the aftermarket heads are the stock 99-04 heads (the ones you have) just worked over. porting, cams etc...
