    185 experts please double check this combo Thanks

    03 GTX 185
    Fresh supercharger rebuild by Jerry with green wheel (riva gen 2) wheel
    215 flywheel and charger gear
    RRFPR set at 60 psi and setup with rising rate 1:1
    Stock ecu for now 215 v tech tune soon
    Upgraded RXT drive shaft and 14/17R solas prop

    With this combo work with the stock tune for a few weeks or should I get the ecu tuned right now?
    Is the fuel pressure set correctly for this setup?

    Thanks!

    What is your air intake?
    Any external IC?
    Any exhaust mods?

    Your ECU will hold you back. Monitor your AFR and see how it goes.

    Why are you using a rrfpr on basically a pure stock ski? 60 psi is probably pig rich for those little 38 injectors. The ONLY correct / safe way to know the correct rrfpr setting is to monitor your AFR - anything else is plain guessing and potentially dangerous.

    The stock rpm limit is 7650 and the 215 HP limit of 8200 will work fine, as many other guys have done, pitching for around 8150, but only with proper monitoring of your AFRs!

    IMO, adding an external IC to this ski will really wake it up.

    My wife will cut me off if I do anything else to HER ski!!!!!!!!!!!!

    I just want it to be exactly like a stock 215 for now (minus intercooler). next winter forged pistons and more mods. (if the funds are available)

    forged pistons, valves, intercooler are on my to do list for next winter.

    If i set it up like a stock 215 the fuel ratio should be ok for a season??

    you should be fine at stock fuel pressure, try and get the rpms at 8150

    To the OP, can you clarify if you're running the stock 185 ECU right now or the stock 215 ECU? 8150 is 400+ RPMs on the limiter for the 185 ECU.

    at minimum you should consider pulling the reference line on the RRFPR

    I did buy the v tech hand held, but v tech dose not have my ecu on file so I need to send the ECU to Jerry so they can do something to it to make the hand held work.

    I wanted to take it for a short 10-20 min ride to see what its like before sending the ECU out.

    Stock ECU soon to be v tech tuned to 215 specs, see above post #9

    What do you mean pulling the reference line on the RRFPR? Are you talking about the rising rate vac/boost hose?
    Wouldn't the extra fuel in the higher boost be a good thing to keep my cast pistions cooler? probably run rich in the boost but help save my pistions till next winter when I install forged???

    Stock 215 has 58 psi?
    only thing is I dont have a intercooler and I have a green wheel.

    Do you guys think I need to monitor AFR on this "simple" setup?
