So I purchased a Magnacharger TVS1900 for more towing power on my 04 2500HD used the included SCT to flash it, and now I want to fine tune it properly. I have read that safe AFR for FI is around 11-11.8? I'm using 93 octane from the pump, I just installed my WBO2 and I am reading around 12-12.4 WOT. So I haven't been stepping in to it at all till I get this figured out, is 12.4 too lean? I assume its because the kit is for a stock engine and I have a CAI and a Cat back. Also the kit uses the stock 1 bar MAP sensor, shouldn't it use a 2 bar? I ordered a 2 bar with hopes of converting to a custom OS or would I be wasting my time doing all this? The truck runs great and has a ton more power than it had but I am afraid I am running too lean. I can post up a log file once I get my WBO2 connected to my flashscan (PLX had to order the TTL to serial adapter)
Let me know what you think.
Thanks.
