wondering how much power increase i will get with a fastman and how much worse my mpg will get...wanna know if it's worth it, preferably from someone who has it

 

My mpg's went up when I installed a Fastman and a better air intake. gained almost 2 mpg. Others have reported similar gains. Those were some of my very first mods, and I was getting 16mpg mixed city/hwy.

Its a great mod. Really improved throttle response. I highly recommend it.

 

agreed.. I've had mine about a year now

 

same here was my 1st mod, def better thottle responce highly reccomended and you get 80 buck back for sending in your stock one

 

he stopped the core charge. i was on the phone for about 20 minutes with him the other day.

 

so is it cheaper now, is he not interested in cores anymore ?? thats weird

 

Probably has enough cores and not selling many of them nowadays. Our trucks are 10+ yrs old!

 

Back when I bought mine, he was desperate for cores. Wonder if the end is near.

 

he told me that they're easily available now a days and that he sells the modified throttle bodies so cheap (compared to a billet throttle body) that the core isn't worth the trouble.

 

I also recommend it. Did exactly what Silver did, "modded" intake and Fastman TB at the same time. Very nice upgrade. Its not night and day or anything like a programmer an be, but you will definitely feel the improvement a little bit. I didn't gain much, if any, MPG because I can't keep my foot out of it now.

While I had it out, I threw on the Hughes plenum reinforcement kit. New plate, new gasket. Solved my leaking plenum issue.
