Finally managed to get my 803s, 3BAR & Bozian chip installed in the track Quadra this weekend - idle is showing as roughly 17 AFR, cruising is approx 16AFR & on boost is 11.8 - 12.2 - now very occasionally the LM1 is showing 20 AFR on boost but its that quick that if you blink you'd miss it must be a matter of milliseconds before its back on track again and it seems to be when you simply go over a bump in the road - connections are all ok to fuel pump etc, nothing obvious hanging off - there was 4 gallons of fuel so I doubt it was surge anyway, plus I was travelling in a straight line!!!

Any ideas???

On the upside she doesnt half seem to go well........all ready for my 3 day track time in France this coming weekend!!!
