I’d like to make a suggestion, put your old plugs back in till it’s running decently then put your new plugs in. No reason to foul up brand new plugs when starting a tune from scratch. I ran stock replacement/ temperature plugs for 5yrs before swapping them. Up to 10psi. Mainly because I was too lazy to swap them out due to inconvenience. Oh and please do not put the gt45 on it since you own the 78/75.

One more thing. Look up the wiring for that MAP sensor and make sure it’s pinned the same as your old sensor. Some require the wires to be moved around.

Plugs as far as heat range were not nearly as different as I thought they would be, looked pretty close to stock. Hey if I foul them I will hit them with a torch and a wire brush!

Yeah I never had any issues or signs of detonation. I had a wire or plug fail about 3 months ago. Those plugs had been in the car since 2016. The colder plugs sat on the bench since 2018. lol I put new wires and the colder plugs in it 3 months ago. Fixed the dead miss.
