I'm hopeful +10 PSi will transform handling but realistic it won't solve much unless other remedial works were done by the builder prior to the previous owner.
I may ship off to Rick Wood a local garageista, as the Peak District becons, but needs to warm up first,
Also I have a engine temp issue as it ran barely on the bottom mark! I did read a post on air locks ( groan) so will try to examine that too!
Any ideas chaps?
