New built cylinder head, can you drive it to tuner?

Hello team,

In the process of finishing my install of my new AMS ported
cylinder head with 1mm oversized valves, 5041 GSC springs.
Also, it is polished and ported both intake and exhaust.

Question, can i drive it to my tuner which is 40-50 miles away?

Thanks

are you still on the MAF or have you switched to SD? MAF will compensate some for the higher flow but you'll need to tow it if you're on SD tune. With MAF, you can try driving it there with no boost and watch your AFR. Also, if you changed your injector size, you'll need to tow.

Start it and see what AFR's do. It'll probably be close enough to cruise it to the tuner. Fuel trims have a lot of adjustment in them.
