I have the exact same combo on my eb bottom end with a standard e series tune 55mm maf and t/b. It runs very well.
It will run lean if you use a bigger t/b and maf.
It is on the limit for the standard eb tune though because ive had mine on the dyno and its around 13/1 afr although ive never had it ping on me using 98 octane.
The guy who dynoed my car told me it will be fine for everyday driving and the odd blast down the drags but refrain from doing burnouts.
Almost 30000km down the track ive had no issues and ive been to the drage 3 or 4 times.
