You'd be very surprised at just how long it takes to flush out the little bits of 98/E85. After having the sensor with the display, there would be no way in the world I'd have the "two tune/flick a switch" junk.
Would be very interested in a back to back between the PT and the BW, after matty's effort. Both need to be on E85 though.You think the BW would give that much more than the PT?
I believe the single flange is a little more open than the stockers. No big deal either way, grind it out to gasket size and do the turbine housings while the turbos are off. All possible differences are taken care of
Injectors, pump, ecu and tune.Pump, ecu and tune you'd be doing anyway. This leaves you space to move later on. Will idle and drive well. No brainier really.
Although not micko's car but tuned by the same guy, mine according to the AFR gauge is 14.4-15.3:1 on cruise. (That's petrol AFR numbers obviously as the AFR meter doesn't know what fuel is in the tank). I can't see micks being any different.What I have noticed was when it dips leaner than 17.5 it gets quite sluggish.. (There was just one cell which needed a touch up. Sorted now)
