My understanding is that currently you cant get a four injector P8 board to run the boost pot and ALS. I believe that you can go to the 8 injector version and run both ALS and boost pot but its more money again.

I have mild ALS combined with lots of power and low weight on the Westfield and it works really well. Map based on the mountune software. Same as mike with the idle speed from cold. 30 Seconds max to artificially hold the revs around 1100 and then idles fine. Thats also on 850cc injectors, not greys.

Must admit we did some low rev mapping and cold start mapping from the original when it was on greys and its made it much better. Not sure how much the more modern 850cc injectors contribute here???? Maybe someone like Mike/Stu can comment??

I fitted a switch to disable the ALS valve separate to the main ALS ON/OFF switch as I was finding the P8 primed the ALS valve into the open position upon ignition and caused the engine to rev up to maybe 2500 straight from cold and until I guess enough vacuum was made to pull it shut again??

In summary, it works well for me in MILD form, but the noise if F*cking loud!!!! Remember my exhaust is maybe only half the length of your cossie oness and exits about 24 inches from my head so flames on ALS and overun can be interesting, especially the daytime when you cant see them to lean away!!!!!
