Dead Serious

Usually PCV oil burning occurs making right turns when oil gets coaxed into the PCV on the left side of the valve cover and then through that black hose into the intake. Thats what Viper was pointing out. The tail pipe will smoke mid corner and a catch can deals with that. During the summer I attribute 5 or so MPH at the end of the straight to intake air temp late in the day combined with a hot, greasy track hampering exit speeds. I think your best bet is understanding whats going on with coolant/oil temps. Try bleeding the coolant system because its easy and free. Who knows if it was done effectively when you had the koyo installed. If the temps get too high the ECU will absolutely pull the engine back. My experience with fuel starve is the engine cuts for a few seconds making left turns when there is less than 2 gallons in the tank.

Couple things.

Would a MAP sensor issue cause the engine to run hot?

Fuel starvation can occur with far more than 2 gallons in the tank

The smoking from oil getting into the intake can occur in right or left turns.

This happened to me this weekend half way through turn 1 at Summit Point (right hand turn). I attributed it to fuel starvation as my tank was getting really low. i pitted in, refueled, and headed back out. No more issues....
