I have had a fleet of vans on LPG for18 yrs,& trust me,once set up properly on a dyno,they are fine.

LPG is very touchy & is affected by manifold leaks,airflows,etcLocating faults is very difficult without proper diagnostic equipment,unless you have lots of time & like getting frustrated

Good luck
