Leask WUR question

When I decided to run a 1 bar spring in the WG, Leask suggested I use a IA modified fuel head and his rpm solenoid valve. Since I installed all of the above, I've been using my PLX -AFR/Boost/Vac gages to tune. Leask's adjustable WUR is easy to work with but I seem to be having some trouble with the enrichment.

Brian Leask said that when running a 1 bar spring, enrichment pressure will probably sit at 2.1 - 2.2 bar in order to create an 11.8- 12 AFR. On WOT, I am getting a 10.5 AFR whether I am set at 2.1 bar or 3.5 bar. I've leaned the enrichment pressure enough to assume there is a problem that is causing a rich condition on boost.

My O2 sensor is unplugged as always.
The PLX does not need to be recalibrated

If timing is too far advanced, can this cause rich conditions (besides the detonation grenade)?

I'd like to know what you guys with adjustable WUR's are running for enrichment pressure?

Any suggestions????

Help.

Thanks,
Doug
