I see that you did not go full throttle the max that you was is 87% check your throttle cable and adjust it if needed or chek if the floor mat is under the gas paddle

what is your intake set up ?

That tune is not suitable for nitrous nor for NA.

Also, not mentioned in your other thread, spark timing has been bumped up but we don't know your cam overlap...

Log file shows 30 degrees ignition advance at 6000+ rpm with significant load...

and tune shows that your knock gain/rate/limit tables have been zeroed (i.e when knock occurs, you will get zero KR)...

do not run nitrous with this tune.

Man I wonder why I never saw any KR, so I thought I could add timing I will take back down, He had it at 28, so basically I got robbed this tune is terrible

You'd be surprised how little timing these engines need. You may not even need 28, most cars like 24-26. As far for 100 shot, you'd probably want to pull a few degrees out which might be dependant on what fuel/plugs you have in it.
