Default Running rich 12.0-13.7 @ idle

So I just finished my vf34 swap and I noticed my WB was reading very rich at idle. During normal cruse its 14.7+-.8. The only thing that I did weird was I took the tgv sensors off and luded the mating gaskets. I noticed the flap slamed shut so I preloaded them and reinstalled the sensor.. Since it only seems to happen at idle it makes me think I didnt get the tgv senors on there right. I cant seem to find a proper sensor install instructions.Now I havent gave it WOT yet... Still data logging but nothing standing out like a sore thumb..

Ive looked over all my hosesmose of them are brand new oem replacements. so I can kind eliminate leaks to an extent..bit the wild card is that the base map is for a vf39 &GM EBCS while I have a vf34 & grimmspeed ebcs. Now im not sure if the wgdc would effect it enough to do this so advice is appreciated

The WGDC has nothing to do with fueling. Sounds like your front O2 sensor is taking a crap possibly.

thats why putting in bigger injectors without a tune will do that!

It doesn't state the base map has the injectors

You need to rescale your injectors. For pinks your Scaler should be 552.47 and your latencies should be

6.5 9.0 11.5 14.0 16.5
2.79 1.49 0.98 0.68 0.38

If they are already set to this, either you have an injector that is sticking open or your front o2 crapped out again. To test for the o2 just unplug it while the car is at idle. If the problem goes away it's your o2. If not its a sticky injector.
