Burn down Bender RX1

[onrof]

No, I didn't burn down...yet. Was wondering on the stage two turbo, for low boost they say to run the 700 main jet in the vent charge tube. Are we supposed to always change to the 400 main jet when we run high boost.?

My sled runs 8 low and 12 high boost and I have never changed it in two years until last night. It seemed like the back shift at high speed was much better, no blubbering etc. Question... does the sled run leaner with the 400 main jet since less pressure gets to the vent tube?

what's everyone else doing?

400 jet is Richer than 700 jet , Pressurizes the vent system more

thanks, don't understand why....but that's what the bender manual says. Do you always change it to 400 for the high boost and is it too rich for the low boost setting. I usually always leave it on high boost with just 93 octane. Maybe i'm just lazy but I want to know what I can get away with.

I would leave it in on low boost too , as long as it still runs O.K
