You'll be fine in map 3 as a daily as long as you're running 93 octane. |
I just did a few full throttle pulls in map 3 and the car had a lose of power and wouldn't shift out of 5th gear I pulled over and popped the head and my turbo was bright red i have no clue what is going on |
There has got to be a coolant line issue or something going on. Plenty of cars running higher than stock boost without issue. I can't believe a piggyback would do this after a few pulls |
Just did some more runs and it losing power around 4th gear in map 3 under full load. I went down to map 2 and it was fine on the next run. Problem is I don't feel much of a difference between map 2 and stock
