406 pump mods
#1
hi folks studied the guides and i am after more power so ....
i run veg oil
fitted turbo boost guage peaks at about 18 psi
bosch pump fitted but with armour over it so started with lda
pin grind .
i notice the side pin only comes out maybe 4mm or 5 mm so this would be the maximum it could achieve not matter what the pin shape .
so ground pin similar to pics on guide ...seems to have more power though turbo boost guage went only up 1 psi ...
removed the plastic washer to give more travel

so next i am thinking of altering pre load guide is saying to raise the spring seat height so that it needs more boost to actuate the lda pin ....some other guides are saying do the opposite... whats the theory behind this please

and again some people are saying scew the smoke screw inwards and some are saying outwards ...
cant get at my max fuel screw yet until i get around to removing armour
and getting at the turbo looks tricky to get more boost== is this possible without removing engine
bearing all this in mind is the governor mod worth doing ....
looking for as much power as i can get towing a caravan lol
