Bosch Pump Chatter

With regards to off boost smoke/better LDA control, you need to look into making the follower pin/dowel move further across under WOT, as standard it only moves into the LDA pin about 5.8mm, at best! Thats if your pump isnt uber high mileage or you have ran it with a rough surfaced LDA pin - both of which will mean the follower pin has worn down and will be shorter than stock!
