Hi Durango Experts,

I know a lot of you have CAI, and have upgraded your exhaust systems. Has anyone also swapped out their throttle body for a larger bored one? If so, how big did you go and do you see a noticeable improvement over performance/MPG?

I'm just wondering if this will squeeze out the last bit of performance out of my HEMI.

 

BBK offers one but imo until a tune is offered you won't see much benefit.

 

Thanks Cmil - I'll hold off then.

 

for the 3.6 guys...thefastman.com offers an 80mm tb...$250 shipped and then $100 when you return a core...so $150 total.

 

I have one on order by the way...LOL

 

Any idea of his pricing for the Hemi bro?? I'd be interested once a tune comes out!

 

the wk2 jeep guys have done a lot of research and the hemi seems to have some room for the added air the ported tb supplies. Theyve had some positive results without a tune. The 3.6 really rsposnds well

 

Might have to look into it then!

 

Thanks for the info Gents! I will be looking them up as well.

 

After buying the bbk and throwing a code I returned it and did way more research. My new Modern Muscle 85 mm <stock ported tb> guaranteed to throw zero codes as they did plenty of in house research, and it yields 10hp/10rwhp though out the entire curve w/o and not requiring a tune. I'll be pleased with the increased throttle response. I was sketchy at first but after reading there product feedback on othe LX forums and speaking with them personally, I feel really excited.
