So I know this is not optimal but I have an exhaust leak between turbo and turbo DP (O2's) but I would like to start my tuning. I understand I won't be "dialing it in" yet but my LTFT are super high (likely due to my FI swap to 60#ers) and I want to at least bring those down. I will be disassembling my turbo when I install my P&P heads next month. I guess I'm trying to avoid having to do it twice if possible in the mean time.
The question is "how much does the flow versus gas concentration matter when gross tuning for streetability?"
Also, in PT 1.2.3e I can log the egr voltage which will become my WB voltage so, what is the conversion formula to see AFR?
TIA,
Slim
