ive been thinking about getting a new tb from fastman. what exactly does it make a difference in? any info would be appreciated. thanks much.

 

For your 5.2ltr, the Fastman TB in a 50mm size makes a nice difference in responsiveness. You may feel a bit of a power increase, but what will be more apparant is how smooth your acceleration is. You will also get a mild improvement in MPG too. Definetely worth the investment IMHO.

 

agreed... put a 52mm on my 5.9 and it was awesome. when I sold my truck I took off the headers & TB to sell and went back to stock, man what a difference it was going back to stock...

 

thanks for the info.
