I have a 1989 gt, as far as mods go i have moroso in fender, 70mm maf, 70mm tb, perfromer upper/lower, e-303 cam, bbk full length headers, off road h-pipe, no cats/smog, spintec mufflers, spec racing clutch, 4:10s, and a 100 wet shot of nitrous. I plan on getting either 24 or 30lb injectors, a 255lph pump, and a fpr, and well i feel that a good tune would help bring alot of these mods together and was wondering what you guys think would work best on my car, is anybody using sct's chip, do you like it? also i live in denver and my track is ay 7000 ft. altitude if that makes a huge difference between which chip, any help would be greatly appreciated

I am not too familiar with the SCT tunes, but you would need to hit a dyno, correct?

The big concern I would have with your combo is the N2O. The rest of your setup shouldn't 'require' a tune (but some have reported drivability issues with the E303 cam).

Any of the tuning systems you mentioned will get the job done. If you have time to learn how the Ford ecu was programmed (and the patience) then the TwEECer RT is a cost effective choice.
If you just want to plug in the tuner and start making changes, then the PMS may be a better option. (you will still have to do some reading, but not as much as with the tweecer)
If you don't have the patience/time to tune the car yourself, then hit the local dyno tuner and let the Pro's do it.

Notice there was no mention of your *current* tuning knowledge. You can learn what you need to know if you dig through the internet...

Hope that helps,

for the tweecer you need a laptop correct? where can i find more info and prices on the pms, also my car is it 14 degrees of timing and the tps senser is at .93 volts. the sct is a chip that is installed in your computer relkatively easily and they custom burn it for you based on your mods and you can get as many tunes as you want and switch from tune to tune with a small dial and the chip runs around 330 all saide and done with 3 tunes

If the SCT tune is done on a dyno, then I would say go for it.
If they create a tune then mail the chip to you, then it may not work very well, it's hard to say.

You will need a laptop for the RT, if you want to datalog.
Check Anderson Ford for the PMS info.

Setting the tps to a specific value is a myth. As long as the tps is between .6 and 1.2v, the computer won't care what the actual setting is.

With any of these tuning systems you will be setting the dist back to 10* of advance, and then make timing changes in via the tuner.
This is a much improved way of setting timing.
