Tunning question

[Gravy]

Cracks around my waste gate lines on both sides, fixed the leak and now the afr is much more stable. Took it for a few spins and got 111% and 115% IDC on e-85. Either i'll have to stick to 92 or upgrade to the 550's again.

One thing i have noticed, and i'm not sure if it's something i havn't been able to find or just isn't out there. But both of my 02 sensors cycle the way they should, but on the wideband, since the day i've had the car/wideband in there. It will start off cruising fine at around 14.5-14.9 and than as i've heard nytrider describe in the tuning post on 3si, it "Switches" from 14.8 or so down to 11.4-11.5. It will continue to run at that range untill i let off the gas and register 0.0% on the tps, than it resets and runs there for a minute or so, than will switch back. I tried tuning for the higher afr range and the lower. But it still switches no matter what.

So if i try and tune it to run on the "High" setting as i'll call it, it runs great for a minute or so after getting in gear. When the minute is up, it switches to the "Low" setting. If i tune for the low setting, it starts off in the high, than switches to the low and runs great. The problem is it is runing super lean to start with and i can't get on the gas at all without terrible knock and a heavy miss. Everything on the logger looks fine, i throw no codes and the only lite on the car is the SRS for the airbag.

The only thing i can think of, and it still doesn't make sense, is the car is set up to vary the voltage to the fuel pump, but i have a rewire done. So it just sees a higher voltage than it probably wants to see. I've tried re-setting the ecu(pulling the battery over night) and trying to get the car to relearn the fuel curves but with no luck. The EGR system is removed from the vehicle, but i've had that on and still had the same problem as i do now.

Any ideas on what to check? Full out boost leak test is coming, i just have to get a couple 1 3/4" caps to put on the turbo's and tap a tire valve into them.
