Ok so i finally got out in between the fog .. I can def say i tried a -2 imco an it sucked! First run was w a 32 maximus w 15 5/8 dia. boat planed well but top end close to 95mph boats ass got loose had to back out of it at 5800. Next i tried the -2 w the 32 bravo that i used w my first run w stock lower which boat ran rt about 100. With the -2 boat only went 82 at 6000 rode like a bag of ****. So now im goin to my original set up w was my fastest set up w my other engine. Stock lower w a hydro p5 only thing is i need to get a 32 pitch.

I started my new setup with a -2 Imco and my slip was 30% . The only time it came down was at wide open with a P5 on it . I ran 96 mph @5900 but in effort to not break the XR I've really have been trying to run Bravo's so I started throwing spacers on there, 1/2" then 1" and now 1 1/2" but still was running out of prop . Last time out was 104 @ 5900 pulling back .. I've got some more props in but winter sports have began so it will be spring before I finish my tuning .
Long story short , -2 doesn't work on my boat !

You should call Brett at BBlades (or whoever you labbed it with) you are using the wrong numbers in your slip calculation for a "labbed" prop.
At 32 isnt a 32 (for prop slip calculation purposes) after it is labbed its considered more of a 31 or maybe even 30. After you use a more appropriate number you will see the slip numbers get more in check.
