Hi, since im turbo, I feel the gas consumtion is sooooo much more than w/o turbo. Ive fill up with 94 octane and If I just spool sometime to max 6 psi at this time I can see the needle go down much faster than before. Im on fmu with stock injector. Is it normal ?

more air, more fuel.

Keep your foot off the gas.

if its a huge difference, did you plumb the FPR right?

It normal to use more gas under WOT, however on the highway i actually get better gas mileage around 38 MPG (yes i think that pretty good!). Of course im using a POS S-AFC (soon to be a 8-injector setup). What i did was drive around with my laptop and scantool and adjusted the S-AFC so the my fuel trims were back close to stock for out of boost conditions. Around town i get about the same mileage as before i was boosted mabye a little less, so keep your foot out of it and you will be fine. Good Luck!
