Default lost and running rich

I recently built my 05 STI. I am running a short ram intake, hta 68 turbo, 740 cc injectors, 255 lph fuel pump, forged cp pistons, forged eagle rods, arp everywhere. Anyway, I recently got tuned and the guys at the shop noticed a bit of a fuel smell. When i got home, i drove around for a couple miles over a period of a couple days, then my injector oring blew out. I replaced the oring and put everything back together. Now the car runs stupid rich (11.1-11.4 A/F ratio on AccessPort) just at idle, light load, and when on the gas. I thought maybe the tuner tuned around the leak, so i swapped back to a break in map that ran well before i got tuned. Same problem. Any ideas? Maybe my spark plugs are screwed or some sensor/electrical problem. I am lost. Thanks

josh,

that means you had a fuel or vacuum leak when we road tuned the car.
but there were no signs of it.

but the closed loop stuff..not on boost light load..put-putting. should be close.
but it sounds like the injector scalor is off..based on cobbs method of adusting
for larger injectors.

please clean maf sensor and double check all clamps around intake manifold.
also double check all the work you did when you took off the intake manifold.


what no call?
