judging from that dip in power around 6300 rpm u are running the 6MT map. switch back to the 6AT low load map to smooth that out. amazing how everyone is replicating big numbers with the same setup.

How much would it cost me to get the JB4 + back end flash? FYI, I already have a Cobb.

Could I still use my AP to log and view gauges or would I need a laptop? This is some serious power!

Logging and hijack gauges would be done via jb4 interface and a laptop. Although I've been using the android app made by n54mike that lets me log from my phone. Then I upload the datalog to datazap.me

I just posted up a new thread to ask views regarding methanol injection over E85 alone. Can you fill me in a little on the difference between running methanol injection over just pure E60 alone? I am currently running E77 on map 7 alone, semi FBO ( no intercooler yet )

Thx

You will lose the ability to log with the AP even when you are driving in map 0. the JB4 G5 ISO will be constantly using the bus and you won;t be able to use the ap except in map 0 when the car is off (to flash for instance).

is your car tuned for ethanol?
