An optimized 87 tune is still better then the stock emission regulated parameter tuning and on top of it the trans tuning will make a difference over stock.We can disagree here. I’d have to see the results to become a believer.
87 octane and tune shouldn’t be used in the same sentence imo.
I think you underestimate how dumbed down factory engine and transmission tuning is for comfort, gas mileage and emissions.
