    Steve, as long as you stay with the stock ecu you dont need to do anything and it will still be very reliable with any of the high boost chargers available.

    Yeah, I think you might need the block guard at 15 or above.

    I don't think the stock ECU will go to 15 without some type of fuel supplement.

    I don't know about the ECU. I'm just saying for the sake of the internals.
