Whats up guys. I came across this website www.thefastman.com and asked the guy if he has a TB that fits my 3.7L. He does have them that fit and he says that I can expect to get a way better throttle response and noticable power gains. Any feedback would be awesome! :killtard:

Very interesting indeed! Looks like $180 plus you send them your old one (core). I wonder how much performance increase you could expect. If it was in the range of 15-20 HP more it might be worth it...

A ported throtle body is only going to give you approx. 5-10 HP depending on the other mods you have done to your vehicle. Also throtle responce will be greatly improved.

I would assume that mileage would decrease with this mod as well.
Im not sure that there would be a decrease in gas mileage and if there was it mostlikely wouldnt be to noticable.

I like that one, I haven't heard it said like that before. It is also very true.

No one is running this TB yet so that might be hard to do. Honestly I doubt that they make one specifically for the Commander. Not all 4.7 liter TB's are the same. Mine looks nothing like the TB found on my friends older 4.7 liter Jeep Grand Cherokee

That's expensive for a ported throttle I did mine on my srt-4 I've ported a lot of things and powdercoated them as well
If you know what you are doing and have the proper tools its not that hard to do it yourself. I have ported both TB's and exhaust manifolds before.

I was a little sceptical because I do know that all TB are the same size. They may have different bolt patterns. I'll ask more into it and let you guys know. This would be a great mod to do.
