I did a brazels ultratune on a 2 valve ford V10. Mine was one of the first, perhaps even a prototype programmer.
The people and products at Brazel's were AMAZING. They asked and listened to what I wanted and needed, mostly because the V10 rev's too high too often, and downshifts at the sight of a hill on the horizon.
They did 3 custom tunes for me before we decided we was good.
And no, the 99 V10 never detonated, and it never spit any 3 thread spark plugs out the fenderwells.
Just as back in the old days I spent a lot of time playing with Holley main jets and powervalves, as well as distributor advance springs and weights, I'm not a fan of "one size fits all" tuning.
Especially now, when emissions and MPG testing costs so much. Manufacturers save a fortune if they only have to certify a particular combination once.
