I am assuming that the SP turbo will be fine with the AFC settings at zero and at low boot (14psi) until I get it tuned. This of course assumes that you don't exceed the metering capacity of the stock MAF. I was just curious what your AFC was set to after tuning? I will be going to Turbo Tune next week to do the tuning.
I have the stock turbos off (what a pain). Now when UPS arrives today the installation will begin.
Well, I've got a VPC so I dont know how bad that'll make my settings differ but....My AFC's settings are a little jumpy. At 3000 its +4% and 3500 its +6% but once the turbo is all the way on I start leaning it out. It goes as low as -11% at 5500. My VPC is also at -6% on the gain knob. Overall the car runs super rich without using the AFC and VPC to take LOTS out. I left everything at zero before I tuned it and I fouled a set of plugs in 150 miles. You should be fine............Good luck, shoot me an email too.
