When I was running on my stock ports, I would get about 10-11mpg on 1000cc and 1600cc. Now I am running my half-bridge............

 

.75-1.0 miles per gallon

 

Lupe who is michael savage and that weird picture on your avatar. Your name may change but you cant change car im new around here to this forum but im from st. louis and all i hear are bad things about eric cheatham more like CHEATham is what my buddy uses you ripped him out of $1200 along with others I guess we know where you get all that money to build your car. I just call out bad guys when i see them

DONT GIVE THIS GUY YOUR MONEY!!!!!!!!!!!!

 

dammm ... my car is untuned .... im not ever in boost .. always in vac..... gettitng about 9 10 mpg?!?!!?!? t88 w 850/1680s Fp ... car is shooting out raw gas sometimes!!!! interesting when i gets lit on fire and it shoots out those crazy *** 4 foot flames

dont worry tune coming soon......then i might get 1 or 2 more MPG ha ha !!!!

 

with 427hp id get 310miles on a full tank!

 

On mixed street driving with a fair bit of smoking people... 10 mpg is pretty typical.

On a long trip (2-3 hours) with a lot of constant speed cruising, I can do around 20-21 mpg.

 

25mpg from NC to WI (1333 miles) that's without cruise control, and light boosting on a PFC base map, intake/exhaust.

With my new motor goodfella is building me, I'm hoping for low 20's with cruise control and no boost. Street port.

 

The key is in the tune. Stock ecu is set rich naturaly to prevent poping your motor.

 

thats basically exactly what I get as well.
