    It’s set at +1. It’s the max. For Moparguy, before repiching the impeller, I think to maptune the ecu with the 8350, removing the flame arrestor from the manifold and see where I am.

    If you are only pulling 7700 now, a tune and IMUK. Is not going to change the fact you have too much prop. Repitch it to 14/17 and you will be golden both now and with your intended mods.

    Supercharger rebuilt, intake manifold, new oil, filter and sparks, applied Maptuner riva stage 2. Already had riva power filter, free flow exhaust, fizzle gen x Intercooler and solas 14/19 with metal ring. Results: still 7700 rpm and 67mph. air temperature 90 F. Sea water temperature 85 F. It really the case to repich now?

    I had the time to do a log with datalogger in the water today. I am not an expert, but first I discovered that exhaust temperature is inconsistent, -136,5, I suppose that the sensor is not working or disconnected, anyhow the ecu is reciving a fake information. No alarm at all. Maximum rpm is around 7650 (the peak when I jump out from the water is 8900) and the boost at 7650 is 8,2 (at 8900 it reaches 11.2 psi). MAT is around 40-44 deg, engine temperature 87 deg. Are these values normal for you guys? Do yo think the exhaust temperature too low may lower performances or definitely is only an impeller pitch problem (Solas 14/19)

    Another thing that I noticed is that igncyl3 at full throttle is always 3 deg higher than the other two cyl (35 vs. 32) Can you expert guys help me to understand if there is anything wrong?
