Check engine light :(
P0170 and P0171
Malfunction and to lean.
These codes keep coming up every few times I drive the car.
They started after I installed the Greddy Turbo Kit.
It says that the system is too lean but my air/fuel gauge says other wise 10.5's/11's/12's
So im thinking its somthing else but not sure what. what could be hooked up wrong to throw those 2 codes.
otherwise the car runs good. :/

its in your tune. 12 afr cruising is fine. but you need to watch our afr at wot. the numbers you gave doesnt quite help. get on a dyno or whoever tuned your car to tune your car not at just wot but cruising as well in all gears. those who just tune for max hp at wot for a street car is a NO NO

I see well it seems more like an install error like maybe I hooked up something wrong. at WOT its around 10.8 to 11 but it never pops up when im at wot it only does it when I turn on the car or get gas or somthing.

be sure to get the freeze frame data so you can find out under what conditions the code came up. I get these buggers all the time when I'm idling (800 - 1000 rpm)

Im hoping it doesnt come back iv removed all the pressure taps that were on the fuel pressure regulator, the boost controller told me to , and hopfully it will correct the problem. so far its been fine put like 50 miles on the car today, guess i should get gas lol see if that tiggers it.
