B/c of an issue with my fuel controller settings being adjusted unknowingly. The #5 and #6 pistons melted.

The supra retained all its charateristics after the rebuild. However, I have not hit boost above 12psi or pass 4K rpm yet. I am running the exact setup so is a retuned needed? Since everything is technically the same as before.

Thanks all!
