After driving it for awhile I had some problems with keeping the engine cool at high speeds, above 75mph to be exact. I blamed two things, 1st I kept A/C so with the added FMIC and bigger engine, I wasn't getting enough airflow across the radiator. 2nd, the tune was too lean and causing excess heat at cruising speeds.
The fix: -Cut a new opening in the front bumper ( I didn't want to do it but I had too)
-Get a new tune
New numbers dropped to 320hp 301 tq
