    At just cruising speeds my 48's seem to be about the same as stock. Under boost, alot will depend on what charger, ecu, etc. you are running. Mine with a Riva pro X charger and Riva ecu are not to bad.

    +1, At cruising speed about 5K off boost they all get about the same gas mileage. I run 80lbs and get better mileage off boost than my near stock PX. Just depends on your complete set up.

    slow down..it isnt just throw them in... you need a way to adjust your fuel map to compensate..usually a rude controler..and keep your air fuel ratio correct or milage will suck...

    the reason people add bigger injectors is to keep up with the fuel demands of bigger chargers...they all have a way to pull fuel off boost..to compensate...

    but they are correct if compensated for they are the same as stock for fuel milage..

    see list below..i rode with my sister she was on her stock gtx ..i wasnt any where near big boost... her ski does 60 =65 maxed out ..at the end of the day i filled them up we had used exactly the same amount of fuel...she was flat out i was 1/2 throddle most of the day ...

    Whoa! Wait a minute! lol I'm not doing injectors. I was just wondering a fuel consumption, which they answered. Thank you!
    I don't plan on injectors, because i still have 3 years of warranty. Yes, i do understand on the mapping and etc.... You never know, someday/year i might need more boost! lol
