1999 pontiac grand am gt help


Recommended Posts

I know a lot of the threads are about older pontiacs, but i have a 1999 pontiac grand am gt and its got quite a few mods and i was looking for advice on where i would be able to find a in car tuner or any tuner and if i need a chip too so i can get my car to how it should be running. Performance wise i just have a CAI and flowmaster/magnaflow custom exhaust. Any help will be aprreciated

What are you looking to tune for? Just these mods? Bump up to a higher octane table? 


 


A "chip" will be worthless, don't buy one of those online. It may even ruin your car.

I was told with my intake and exhaust id have to buy a tuner to get the full benefits out of it

In my experience, I wouldn't say you need to but you can definitely take better advantage of both with a tune. Are there any plans to do anything else with the GA?

With only a CAI and exhaust, you'll find that the cost of tuning won't really gain much in hp.  I think Milzy still tunes GA's but I'm not sure.  There's very little aftermarket left for these cars and not much hp gain without some major engine/trans work.  Visit GrandAmGT.com for more GA specific info and some sponsor links to the few guys who still offer parts/tuning for GA's.

You could buy HPTuners. It is an expensive piece of software, but it lets you make a lot of changes to your ECM calibration. It works for many, many GM models. I have found it indispensable and use it on all of my GM vehicles. You don't need to have modifications to benefit from a few changes to your tune.

Be forewarned, you should really look into how to tune your car before you start making changes. Lurk on the forums on hptuners.com for a while and learn as much as you can.

yes milzymotorsports.com is still open and still has lots of stuff for them.

a tune can always benefit. Revome restrictions tune for a higher octane will definitely help.
