My biggest thing is I still owe 800$ on my Monte and I have 171,xxx miles on it, so no ones gonna wanna buy it, it still need body work done, there are small dings, dents and rust that need re done so I'm just gonna eventually do a swap and new transmission when it starts to go

 

The hypertech adjusts Rev limit, shift points, shift firmness, speed limiter, tire size, reads codes, and has a setting for 87, 91, 93 octane fuel for "added" power. I would have to double check that it works on the 3400 though. I used it on the 3800.....

 

I don't see the 3.4 listed but if you wanna search more you can. Mine is the hypertech man energy programmer part number 32500

 

I'm pretty certain the supercharger on the Grand Ams was an aftermarket kit. Granted, if you could score one, I bet it would fit well on a Monte 3400.

And this is very true. The 3800 is a great drive train (so is the 3400) and in a ton of GM cars.

I saw another thread of yours about 3400 mods. I believe I mentioned this recently to someone else looking for 3400 mods, based on my experience with the 3400, if you want a little better performance and not a hefty cost (all of this is in great detail in a thread I posted in your mods thread):
- Address any basic 100K maintenance that has not been done
- Get L67 coils
- Cold Air Intake or gut the existing air box
- Delete the resonator
- Consider the y-pipe and dual mufflers (as seen on the SS, this is more for show then go)
- Rotate the radiator mount bushings (or replace with poly bushings)
- Get a better tune on the PCM.

And call it a wrap.

Now, if all you really just want the speed limiter deleted and some trans adjustments, I might be able to work with you on that (as I offer some minor tuning adjustments, thread below):

If you want more then I offer, I would suggest one of the many vendors who are well experienced with these platforms.
As bumpin kinda eluded to, the hand held tuners are a bit weak/tame and with the car being mostly stock, there are a lot of vendors that can do more for you in the $100-$200 range over the handheld unit. And getting a HPTuner or DHP PowrTuner, it requires the money to get it and a LOT of learning.

 

Yea like i said I might just do the pcm, in time either do a supercharger or a top swap, throttle body and and might have it ported and polished
