is a significant increase in MPG not good enough for him?

 

MPG is great, BUT if the truck breaks, then you won't have any WARRANTY

 

Warranty depends on dealer and how bad it breaks

 

Yeah I agree I'd rather do it and take my chances that I'm helping the truck out therefore maybe it won't malfunction and mess up as quick. Ok good glad others agree with me. I'm gonna try a lil harder now. Thanks.

 

we have a 6.4 with chip intake and exhaust with about 65k on it, only problem we've had is some stupid o-ring and thats it

 

The answer is Edge Racing CS, AFE exhaust and level 4. The Avatar says it all.

 

thats just what your dash says though, what is it hand calculated? my 7.3 says i get 29 mpg i know thats far from true

---AutoMerged DoublePost---

our 6.4 gets about 16 in town and around 18-20 on the highway

 

I get 29 in mine......

 

I only get 14 MPG in the city & I have almost 36,000 miles

 

never been around SCT, my best friend has a 2009 6.4 with a spartan, DAMN good chip, has power up the *** and roles coal like no ones business. but it isnt on the fly. i love the fact that i can switch from street to extreme with the twist of a **** in my OBS. he has to upload his tunes and sit and wait for his tunes. if i had a 6.4 i would definitly get an H&S Blackmaxx. my .02
