If it's not a dynojet just throw the numbers out the window and focus on the before and after number gains. I find these numbers hard to believe with just a tune difference and a few months. Those numbers do however look like a gearing change. There's just no way 19.69 peak HP between tuning software unless the uprev was a sh*t tune which I doubt if it was the same tuner.
All are uprev from a customer of mine.
The blue is tuned 4th.
Red is tuned but with my ported upper, lower and TB's added in 4th.
Green is same as red but 5th.
