I was wondering if the Fastman TB are a good deal. I know alot of you guys love these thing but i have no experience with TBs. What kind of power gains are expected with the 52mm TB, 52mm because most of you say that is the good one. And will it still allow me to still use my K&N air filter system??????/


I was also wondering if any of you have used the O2 simms they have. I got a 99 dodge ram 1500 V8 5.9 and its got the single Cat with the O2 sensors in the Cat and after the Cat so will one of there simms work to eliminate the O2 simm inside the Cat. Will it throw any codes??????

 

Someone is on here selling a fastman for $200.

why do you want to sim the o2 sensor if your are working fine? thats a waste of $50. and it won't throw codes... thats the whole point of the sim.

 

Only reason you really need a sim is if you do the illegal thing of removing or gutting the cat, and your computer throws a code because of that. Some guys gut their cats or remove them and still never experience a code. Some even experience a code when they put a high flow on. Only get a sim if you need it, IMO.

The 52mm Fastman is a great upgrade. Very simple. Its the same outer dimensions as your stock TB (he modifies stock TBs, thats why he refunds you $80 after you send him your original TB), so any CAI or 14x3 air cleaner system will fit it just like the stock unit.

You probably won't notice much for power gains down low, at least, not in my experience. But you will feel it with the butt dyno at highway speeds, my acceleration greatly increased at the higher speeds.

 

never seen so many fastman threads geeze lol. if you use the search you will find countless info on it , and people thoughts and exsperiances on it.
