Have a N2MB WOT Box on my GT500. When banging gears @ WOT will sometimes get pops due to fuel building up when ignition is cut during shifts. I know the motors are apples and oranges but have never heard of any damage from this.
Unless your buddy is a real good driver running bias slicks, chances are you could beat him being N/A with E85 and drag radials. In 1/4 mile with the A10 you have such an advantage over stick cars. I bruised a lot of egos of high HP stick car owners running that setup.
2018 with P1X stage 2, E85 with 4.25 pulley. See right at 12 psi.Good pulley size choice it will put you in the sweet spot. Never been on dyno. TONS of power!
I went with Ford X-pipe and it sounds great. However, since I'm not planing on keeping the car for 200K, if I was doing it over would go with a less expensive one.
No need to buy a after market OBD reader. Check the owner's manual it will tell you how to check omissions readiness. It won't define which monitors not set but will denote if they are all set.
