urabuslegacyGT44 Posted September 16, 2012 Share Posted September 16, 2012 so i dumped my pile of parts into the 2008 leggy:(brand NEW parts with 0 miles) TD06 20g turbo, DW750cc, DWfuel pump, Cx FMIC, TurboXS bov, 3inch catless TurboBackExhaust, and a boost controller. took it to a local subaru tunning shop called Equilibrium tunning in Fairfield, CA and he is telling me that something is wrong with my (NEW out of the BOX) injectors and/ or fuel pump. the car begins to run lean when he tunes for more fuel\air. i dont know what to do. should i just replace both the pump and injectors? just the fuel pump? or is a legacy different than a wrx when it comes to tuning? does "S sharp" have anything to do with it? let me know if u have any ideas... or parts for sale Link to comment Share on other sites More sharing options...
charlie_sheen Posted September 16, 2012 Share Posted September 16, 2012 did he do a leakdown test before he started tuning? car looks awesome man Link to comment Share on other sites More sharing options...

wurkenman Posted September 17, 2012 Share Posted September 17, 2012 Should not be anything wrong with that setup. The engine is basically a WRX engine. Car looks awesome. Love the white. If you woke up today, you have another chance to do it right. Link to comment Share on other sites More sharing options...
Spec B Posted September 17, 2012 Share Posted September 17, 2012 Start/focus on the pump. Confirm that your pump is installed correctly - a faulty (or mis-installed) pump will lean out on the high-end. It is pretty rare for the injectors to be the cause of a lean the issue.

urabuslegacyGT44 Posted September 17, 2012 Author Share Posted September 17, 2012 thanks guys for the feedback. I am going to check the pump tonight to see if i can figure anything out. i think maybe the fuel connector might be twisted under the seat or maybe pinched somewhere. I hear that the Datchworks injectors are not very good and same with the pump and i was thinking maybe that might have something to do with it. but ill be starting my own thread as soon as i get that little piece of paper. is there a picture of a properly installed pump that i can base mine off of because i have already pulled it out and nothing looks that out of place to me. thanks again Y'ALL.

TheOneDoubleN Posted September 17, 2012 Share Posted September 17, 2012 There's absolutely nothing wrong with DW, they're probably the most popular option for Subaru fueling. I have however, heard some horror stories about EQ in Fairfield, so be careful. Link to comment Share on other sites More sharing options...
SSpeed Posted September 17, 2012 Share Posted September 17, 2012 My vote is also pump installation. Link to comment Share on other sites More sharing options...
TheOneDoubleN Posted September 17, 2012 Share Posted September 17, 2012 took it to a local subaru tunning shop called Equilibrium tunning in Fairfield, CA and he is telling me that something is wrong with my (NEW out of the BOX) injectors and/ or fuel pump. There are a million things in your fueling system besides the actual pump and injectors that could cause a fueling problem. The fact that your tuner is just blanketly blaming your brand new pump and injectors (not the installation thereof, but saying that the actual parts are defective) is a big ol' red flag that he may have no idea what he's talking about.
