Default Air Fuel Gauge suddenlys goes from 9.0 to 13.5 with the greddy blue box????

Part that was installed was a STR intake manifold, and after, it statred to do this...
Recently my car has been running really lean and i dont know what the probelm is because before the gauge used to read 8.0 and 9.0 with the Greddy turbo kit and know it reads 13.5 at full throttle?? Has my blue box gone dead?

8-9???? you can start your car???? what gauge are you using......i'm assuming your gauge is completely out of whack.....13.5 is on the NA lean side, but 8-9 is off the scale rich....

Gauge is a Greddy A/F
When i drive my car and press the gas all the way down and as it goes to redline the air fuel gauge is climbing down to 13.0
before it did not do that it just stayed between 8-9

Wideband is only way to provide accurate A/Fs.

wideband o2 is gonna need a wideband reader. look for the FJO wideband system. that'll give you an idea of how much it costs.

if you just installed you intake mani, and now you're running WAY leaner than you were before, maybe something's leaking
