Hey guys,
speaking of great power on stock turbos...
Here is a 135i I spent some time tuning last week, mods are as follows.
Stock turbos, FBO, E65, JB4 G5 iso tuned on Map 6, with Trebila Performance E85 specific custom back-end flash and Fuel-It Stage 2 LPFP upgrade.
The car has a JB4/Coolingmist Methanol injection system but at the time of this dyno run a Meth' system issue had not been resolved.
Cheers,
JD.
