Bank 1 Lean

[PilotGuy]

Hey guys, I’m trying to wrap up my Procharger/Fore L2 install now. Got the Procharger pulley alignment issue figured out, now the last thing is Bank1 is lean. Lund suggested pulling those injectors and checking the o-rings. I pulled the passengers side and replaced them with the other o-rings that comes with the ID1050x’s but it’s still lean. Assuming my nGauge is accurate, Bank1 Lambada reads 1.5 and Bank2 Lambada reads 0.9. Is the nGauge accurate? Bank1 is the passengers side, correct? Any suggestions? I read about o2 sensors, so I could try that, but it was fine before the fuel system install.

Still on the stock rail ? Is it lean through the whole pull or just when the boost starts to build?

Fore rails, it’s lean just idling so I didn’t raise the RPMs any.

check for vacuum leaks. If all of that checks out than maybe try swapping your o2 sensors from side to side to see if the issue moves to bank 2

How is your pcv system setup?

I set it up just like the Procharger directions stated. So I capped the line right behind the throttle body, routed the drivers side vent to one of the ends of the T off the inlet tube, and routed the passengers side vent around the front of the car to the other side of the T.

I'm having a similar problem, I wonder if it's a quality control issue with the ID 1050xs.

That’s how I have mine as well. Until I can get or make a good catch can setup. Anyway back to your issue. Check the simple stuff first make sure all your I/c plumbing is not leaking, no vacuum leaks, no exhaust leaks. Is the o ring seal on the maf sensor? Fuel pressure? Fuel line routing

anything is possible, but their injector quality is definitely top notch. If it were a set of eBay injectors or something they would definitely be suspect

Are these the correct gauges to monitor? Is this good now?

Looks good. What was the problem?

I forgot to plug two coil packs back in

Interesting. Glad you got it figured out your well on your way now.

Thanks for all your help!

Leave lambdas and IAT on top right. The rest change for coolant temp, knockR and boost if you have a boost box, or total timing, or fuel pressure (I think 18s have rail press sensors right?)
