Every couple of months i make this 300 mile trip to visit my mom for a weekend, well sense the last trip i installed the 2.8 pulley and 60 # injectors and now instead of it taking me a tank to get their it took me a tank and a half, any suggestions on y????

 

Are you tuned for those mods? I dunno, obviously with those mods its gunna get worse, but a 50% increase in fuel consumption sounds like a lot.

 

Yea. X2 ^^^

1.) Are you tuned for those?
2.) What was the weather like?
3.) Did you put in a different octane? / Fill up at a different gas station?
4.) Were you boosting a lot????????

 

yeah, that's insane.......I think you need a better tune

 

im tuned for it from intense, but i dont like my intense tune, i already ordered a new pcm from zzp, so ill be trying that one out untill this place here in savannah tunes it for me, but i realized when i was fixin an exhaust leak that there is a type of liquid leaking out, like fuel i guess, hopefully thats all it is is the tune though

o yea the weathers cold and i am boosting about 2lbs less after i put the injectors in

 

Assuming no problems with the car. You drove crazy fast? Quicker accelerations and higher highway cruising speeds? Was there a lot of wind?

Assuming there is a problem with car. Leaking fuel somewhere?

Any performance mods that improve horsepower are supposed to make the engine more efficient and as a result more fuel efficient. Did anyone notice that after they modded their car it got better mpg's then before? Assuming you drove the car in the same manner before and after the mod.

With a smaller pulley I think that the supercharger provides boost more easily which would result in more fuel being used. Did you notice your boost levels? If boost was higher (positive or less negative) than you would have burned more gas to maintain the same air fuel ratio. Not sure about this...on one hand your car is supposed to be more efficient from the mod...on the other hand if you are forcing more air into the engine than more gas would be injected which would lower mpg.

 

could i be losing fuel from not having my fuel injectors in correctly??? i noticed the change after installing the injectors but didnt think much of it untill i made this trip

 

herressss your sign

 

get a custom tune. bigger exhaust will fool the o2 sensors to push more fuel to meet the stoich quota as well.
