no you cannot run a cvba2 or any 4 bank strategy on your "1.5" bank ecu. You must run a ccaqa or ccaqe tune
there is no adx file for either of those strats, and I never released my xdf file for either strat as well
the single bank turbo is interesting, im curious to know how it performs
the supercoupe rods and pistons are junk
yea its best you only run premium fuel in a boosted vehicle
If you tell me what injectors and maf you have in her I can post a startup tune for you that would be much safer to run around on now for the time being until you can get it dialed in, I can post a limited xdf file for you to dial in the maf to get the fuel correct, no logging though as i hadn't finish it since no one wanted it.
Your best bet though would be to get a full custom remote tune
