Is it still possible to get good gas mileage if you upgrade to sti injectors or can you tune your ecu to compensate for the larger flow rates?

 

I have pinks, pump, plugs, vf22, cai, bigger top mount, turbo back, ecutek tuning, and usually cruise around at 16psi and I get 19-23 mpg. That's with mon-fri freeway commuting with minor street driving.

 

Do you have any dyno plots of this set-up? I am planning to upgrade to a larger turbo (I assume I have a VF23 on my car. I know it is larger than stock but smaller than the VF34. AND I cannot get to the engravings on the turbo since it came on the car.) I most likely will get a VF22. I am not really interested the dyno plots for the HP, BUT FOR the A/F ratios with those injectors. I have heard they are too small but most people that say that do not even own the VF22. Also what top mount? I currently dynoed 235whp/wtrq (~330chp) on Vishnu's dyno and I want to make about 275-285whp (~380-395chp) on the same dyno. I already have an UP, TBE, Pinks, Reflash (tuned), pulley. I know I will need a larger top mount, but I prefer to not get larger injectors unless they are absolutely needed.

 

I have a dyno chart, but it was before I got plugs, pinks, pump, bigger top mount, and tuning with that stuff (I had it tuned for what it had). Without the above I dynoed 241whp. http://www.cardomain.com/ride/789035

I'm not exactly sure what I'm pushing, but I'm guessing that I'm near 330 hp (not wheel) because I did a rolling start in 2nd with a newer looking m3 and we were dead even. I also had 2 12s in the trunk and a passenger.

 

Are you talking about just changing injectors and nothing else?You need to include more information.
