Can you please elaborate more on the ESS DirectFlash Stage I you have on your 1M.
I just got my 1M and i am interested to purchase the ESS ECU application. They promised: 400 HP and 550 NM of Torque. (thats on the flywheel not the Rear Wheels right ? )
how easy is the ESS DirectFlash to download tuned software ?
How is the Fuel efficiency now in your 1M ?
Having engaged the overboost all the time (550Nm) wouldn’t that cause damage to the engine ?
Sorry for those many Qs , i am just excited about tuning my 1M.
Did you try to install a bigger intercooler and turbo downpipe ? or a cold air intake system ?
