Default Problem with b9
Hi
I have a b9 to replace my grp tuned engine.I have broken the engine in but the engine seem to get very hot 160-180f but does not have the power anywhere near the grp which has had a full rebuild.The tried different plugs rb 6-7 better with 7 ran cooler.But does not have the top speed.
Thanks
