215 ecu on my 185. Re pitch the stock prop?
I have a 06 GTX SC. Due to an ecu failure i now have a 215 ecu running it. My question is can i re pitch the stock prop to get the revs up and take advantage of the higher rpm limit of the newer ecu??? Or is there something i am missing and this is not advised unless i have other mods in place??
Currently the ski is stock except for the flame arrestor in the manifold being removed. I do have an intercooler for it but it will be a while before i get time to fit it. This is more of a family ski and most of my attention goes to my RXTX 260.
On a side note i have also noticed that my max rpm is only 7200, this was like that before the ecu swap. My oil level is at the max mark on the dipstick. Will removing some of the oil really make a 400 rpm difference to get it to where it should be at 7600??
Thanks in advice for your thoughts

removing some oil will help but maybe not 400 rpm. You can repitch the prop to spin higher rpms but did you install a 215 fuel pressure regulator?
I would get the intercooler on before spinning the rpms up higher. did you change the flywheel and sc gear?

I didn't install a different reg. Nor did i change supercharger gear or flywheel. I dont really want to take it that far. Its just a family run around and my attention is mostly towards the tx260.
Doing the intercooler before increasing the revs sounds like a fair call.
Do you think it really needs a 215 fuel reg given that its running lower boost and and lower compression than the 215 and soon to have an external intercooler?
What else could cause my low max rpm if not the oil? Supercharger slip??

you need the knock sensor update harness and a repitch

stock rpm limit for the 185 is 7650. When you get the issues resolved you should be around 8100 rpm with the 215 ecu.
You got something going on to be down 450 rpm with the oem setup! I'd look at the impeller big time, all the easy stuff such as fuel, plugs, boost leaks, wear ring, etc.
