If you are running a tune for 87 octane why run premium? It won't make a difference in your MPG and you are only spending money needlessly using higher octane than you set your tune for.

Yeah, that. Plus, 93 octane gasoline is LESS volatile than 87 octane. That's why some engines need high octane--to prevent knock.

I have no idea what would be normal for your car. If your car doesn't accelerate smoothly, something is wrong with the car or tune. I've had three different tunes on my car and never had any hesitation at full throttle.

It was like 10 degreeS. Anyway lol i just need to wait a couple more minutes before leaving. It would run perfect if i dont floor it but if i leave too soon on cold and hit full throttle. The first pull act like if the timing is way off. A 2 second issues then if i retry it would pull correctly
