Inexperianced and NEED help!!! Please Hello everyone. So to get started I have an '02 Denali XL, .30 over LQ4, mildly ported 862s (I know I know, I'm workin in some 317s), Howards "ASA" cam and enough know how to change the cylinder volume with Hptuners. I really need help diagnosing something before I can start tuning and some advice on tuning if you have some input. My O2 in B1S1 just kinda does nothing and my fuel trims are just f***ed. Its a new sensor and I upped my idle 100 rpm across the board, with Hptuners, which slightly helped it not die but did nothing for my fueling issue on bank 1. B1S1 just kinda sits low and pours fuel in and B2S1 basically does what its supposed to. But another scan I unplugged the TPS (IAC at 310) and you can see B1 somewhat start to work and B2 hit damn near the bottom and start to flood that side. I have no idea what I'm working against here and would bring it to work (Dealership) and have the old (experienced) guys look at it but I can barely move it out of the garage let alone drive the 15 or so blocks to work. Someone please help me, I am new to tuning and haven't learned enough from work to help me. It dumps the fuel in so bad that I have to change the oil now. I'm very confident I have no intake leaks but will be double checking tomorrow. PLEASE someone point me in some direction to start.
