turbo oil leak effects on wideband readings?
 

So I m converting to e85 and I started tuning my ve. Only problem is the turbo is burning oil. Can I finish tuning so I can drive the car while I wait for a new turbo or do I need to just wait..normally I would wait but I m going to be real short on time for the next month.

its leaking on witch side of the turbo? compressor or turbin side? personally i would tune it and then revist it once the new turbo is in place and see if anything is off i doubt it will be but you never know
