It'll be an interesting comparison Phil - mine is running LH2.2 so no Lambda, cat or closed-loop control or fuel trims.
As such whatever difference they make will solely be down to the injectors.
Allegedly they've been despatched today by a 3 day courier so will probably land tuesday/wednesday next week.
Might be a little while until i fit them because i want to make some aluminium adaptors to fit LPG nozzles (spuds) into between the injectors and manifold but i might (depending how much the existing injectors play up) just fit them and have done.
