97 SS252 454/330 hp MPI sluggish on performance
Wanted to see if anyone out there has an 252 SS with 454/330hp MPI, 26p Bravo III, 1:81 to compare numbers with. I'm experiencing sluggish performance, 4200 WOT with new motor. Computer says everthing is the way it is suppose to be,but I'm only getting 4200 RPM @ WOT, 51ish MPH. Guys @ Formula tell me I should be getting 4600 RPM 57+ MPH. Do not want to sink ton of money or take away reliability but would like to get to lower 60"s MPH @ 4600 RPM. Any ideas?

Did the guys at formula tell you what prop came with the boat for that motor?
Is this a brand new motor or a rebuild? What did it run before?
With the base 454 motor I would think mid 50's is all you would see.

It's a re-manufactered motor and it came with the 26p props, the motor is 30 over. Other than that eveything is the way it came from Formula.
