i received my SDC ecu today pluged it in and took it out for a test.
managed 116 kph at 8350 and pump filled with wiggs and plastic, ecu is set at 8550 rpm.
i havent reset the tps and will do that asap..my afr at wot is 11.3 11.5 and my rrfrp is set at 55psi on dess...
can i adjust the rrfrp psi to lean it out to 11.8?? will that affect the low and mid rpm?
its idling at 12.5, while im cruising at 4000 5000 rpm its reading 13.5 to 14 is that safe?..
what else can i try to get my rpm up to 8500..

As Rory has said your okay as is. Read this thread and refer to Donnie's AFR table.
There's also great advice on the differences in AFR readings that Rory mentioned.
Remember "Lean is mean" (until she goes boom, then it sucks)
