Ok I posted in discussion and no help...maybe I'll get sumthing from u guys...I installed the delta 44 previously I had no problems with the car...nowim getting a p0172 code...fuel trim rich or wutever...I'm on stage 2 injectors and all other fuel is the stock...mods are bc 272 cams, bc springs n retainers, arm intake agp coldside with tial bov, potted intake manifold, 3 inch turboback and a big fmic...wut could be causing this problem...at idle it runs rich as a pig like 10-11 afr I had to pull 40% fuel out for it to idle fine but still getting the code, keep in mind I'm only on stage 2 injectors...and when I go to slow down to a stop the car will die unless I rev it and then it starts running rich again and then settles down to normalcy...also I have the bigger spring in my agp external wga with a mbc tapped between the turbo to wga I have the compressor line going to the side of the mbc then the bottom of the mbc goes to the wga...for sum reason if I get on it the boost goes all the way up n past 30 psi...wuts goin on with that? All help is greatly appriciates thanks

What are you using for fuel control?

i have been sent about 4 different maps from performance autowerks on an sct xcal, a few here and there tweaking it, still no luck on it, dave tried pulling fuel and sadly the car just runs worse...i also have a afc controller, which is doing nothing for me it is zero'd out but i tried pulling fuel from that, and no luck, it still runs pig rich at idle, and when i get on it...with 750cc injectors, walbro fuel pump...the car runs lean as heck, so i added fuel with the afc controler to try and adjust a little and it ended up me maxing out the afc at 50% and the car still runs lean...idk wuts going on

Sounds like youre not scaled for the right map and tip sensors. Do you have stock sensors or 3 bar?

I had the stock map sensor and pwerks gave me a map with that...then I was getting a map sensor to high code so I got a 3 bar map...I put that on and drove with the stock map tune and it ran a little better then the next day I got the 3 bar tune and it runs even worse then it has before...idk if that helps at all?
