    So, everything has been solid on my tune thus far. Wanted to get some input from you guys.

    I havent seen knock activity on the car as of yet until today.

    Ive got a 15 with a paxton 3.8 pulley on 91, JPC fuel system, with Fore fuel controller. Lund nguage tuned.

    In 6th gear when i accelerate i can see quite a bit of knock +2-7* ive never seen that. I didnt get that in the log though. Log is 4th gear pull 3-7k. Im not seeing much knock at WOT but any knock is usually not good. Traditionally ive been -2/3* at WOT.

    Ive attached a log if someone could look at it and tell me what they think.

    Log 42 is today 7/26/2018 4th gear 3-7k
    Log 41 is last friday 3rd 3-7k

    If anyone could help me out, would be wonderful.

    When running 91 octane there isn't much of a window for tuning. Avoid acceleration in 6th gear and just use it for cruising. The load that an overdrive gear can put on an engine is immense. You have a high compression boosted car using 91 octane so keep that in mind. If you need to accelerate drop it down a gear or two.
