Rb turbos, meet the 135i
Had a blast setting up the tuning for this 135i, large Asr ic and intake, full exhaust and RB turbos, set up on 91 octane now, but will be going to a 30% E85 mix next and then will be working on getting it to run on full E85. Like this option much better than Meth injection. Been down that road, just too many thinigs to go wrong and its a pain to keep the system working.
