I think my warranty is out in Oct, I am going to double check that. I was looking at going down in pitch on my prop to bring the rpm's up (now around 5500rpm @ wot with a PT ofx3 19p from what I hear it should be closer to 6000rpm) but got to thinking that for a little more money reflash the ECU and turn the prop I have. (new prop $500, ECU reflash $650 from what I have seen in other posts) Any more info on increases in performance or prop changes with going to a 250? does going to a 250 keep the rpms around 6000?
