zzp is limited with only the 3800 powered vehicles. i am glad some one mentioned here about overkill. because i got a messege back that they can give me a tune for my 3.5. it is good to see that there is some one whocan do a wide veriety of tunes for our montes due to the wide types of engines

because i have to replace it anyways... so id rather just remove it... as far as i understand, it may or may not result in any performance gains, but it wont do any harm either, we dont have emissions test here.. so 10$ to block it off vs 75$ for a new one... what would you do?

I've never experienced a tune from ZZP, so I can't talk for it. However, I have the Overkill tune on my 3.5L, and I love it. Worth the money and time to work out a couple minor bugs. (crank re-learn, service traction control, and security re-learn).

ah man, what a difference!, and from what i hear its only going to get better over the next days! no problems at all, just had to relearn my key, took 30 seconds, no need for a CASE... the difference in torque off the line alone is well worth it, had a lil chirp dropping into second gear at WOT.. never had that before! (mind you the roads are a little wet but still!) now i cant compare to other tunes, this is my first.. but yeah, WOW, love it so far... downshifting happens so quickly too, very touchy for that, which i like!

Overkills in car tunes are the way to go, if you can figure out way to get too him. Will has tuned my car twice now. he really knows his stuff. But when it comes to generic tunes, you really cant expect a whole lot as every car responds differently to certain mods. but for getting rid of ses codes and stuff go with overkill as he is only one guy trying to make a difference.
