im running a greddy kit on a stock GSR motor. it has 440cc injectors and its tuned on hondata s200. im only getting 20 mpg. is that normal? can someone give me some advice as to what i need to do.

 

stop beating the crap outta your car....

i had a LS turbo with 450cc injectors on a crx of mine a few years abck and if i recall i got about 8-10 mpg beating the crap out of it...

change your driving habits to increase gas mileage. stay out of boost if u want 30 mpg

 

i dont beat on it. i shift at 3000 rpm.

 

Do you have a wideband

 

no i dont have a wideband

 

reason: bad tuning? str8 pipe if so geta cat+ressinator believe me it save gas! and stock muffler. how much ur boosting? and more then likely its normal.

 

who tuned the car?

 

when i first tuned it, it was getting 25 mpg. it doesnt have a str8 pipe. boosting 7psi.

 

some shop in huntington beach. i forgot the shops name.
