So, basic setup is as follows:

2004 192hp 5MT (the EUDM piece of heap)
Intake modded (plastic plates removed)
BHR ignition kit (coils, wires and plugs)
OMP adapter with external two stroke oil tank

Otherwise running stock. Engine is fairly new with about 10,000km on it. We've been working on the tuned map for a few months now, and I figured it might be time to take it in for a spot check on the dyno.

I'm worried about the AFR at 5500rpm upwards. Search revealed AFR readings of even 13:1 to be safe on a naturally aspirated engine at high revs, but isn't this alarmingly lean?

Thanks for any comments..

Tuners have shown that ~13:1 is the best for power on the renny. The OEM tune goes rediculously rich at high load.

Ok, then these figures make a lot more sense. Thx
