HELP!!! first ride with a 2rude on my PX
Yesterday, I toke my PX for a test and tune session... AF ratio was between 14.7-15.8 all day. I tried messing with the RRFPR and it still ddint change the reads on the guage. I started the psi at 56psi, gauage was reading 15.2-15.4, the i was like ok let me up the psi to 60psi and see if i can get the guage to read a little richer. I did that and the guage reading didnt change, but the ski was very sluggish.
I was also only getting 7900RPMs and only 10lbs of boost.
Can anyone clue me into what is going on with my ski?
Never got around to do a gps run...
les cooke 8600 ECU
Les Cooke valve train
trd waterbox w/tru hull
aeromotive RRFPR set to 56psi

On the wideband. If its the small one it does not need calibration @ all (which is why I own it). Its a nice unit as long as you can keep it weather sealed.
On the AFR. You need to know what that ECU is mapped for.

Try turning FP up to 80psi and see what it does.
You are so lean, you are going to damage the engine.

and yes i have a pressure gauge that i can read when riding... and there is rise.. starts at 60psi and rises to 70psi...
well b4 i toke the ski out for the first time, I email Jerry and had him look over the setup.... he said i had everything to run the 2rude... and he recommended to set the RRFPR to 56psi..
I will try turning it up to 80psi.... but when i was riding yesterday, the more i turn the pressure up the more sluggish the ski was. telling me the its rich... im gonna check the spark plugs tonight..
