I am running near 30psi and have a dsmchip with fuel cut removed. Timing is 10* due to the high flow of air, 3200Hz per KEYDIVER. I get a quick "burp" or "mini" fuel cut. I have a Walbro 255 rewired, BRP7ES plugs gapped at .025". No knock, A/F around 11:1. I cannot figure whAT IS CAUSING THIS ABRUBPT "burp". Fuel pressure is set at 40psi, hose off as is programmed into the chip. Any suggestions from guys running high boost/big turbos?
I am going to back the boost a few psi and see if that helps. It seems the longer I am at this high boost condition and revving like in 3rd or mostly 4th I get the condition, not in 1st or 2nd as I am at redline so quick. I have one suspect coupler to change and then I have exhausted what I can try to resolve this issue. Thanks, Mark
