you could look at your spark plugs and get an idea about your condition, white and chalky means lean and black means rich. chocolate milk color is about what you want. an aftermarket boost gauge will tell you to the exact presure that your turbo is doing. the stock gauge is not very precise, and not as easy to read. it works fine for stock applications but if you going to modify one you should upgrade your gauge. i just bought a vdo gauge for 30 dollars last week. when gorfllub and i were having a similiar problem another member told me about a article on clarks garage that explains how to get trouble codes out of the klr unit, that may help you. did your car do this before you had it serviced? are all three of the hose nipples still on your cycling valve?(round plastic valve under the intake between cyl. 3 and 4) i've heard their bad to break off. also check the hose all the way to the wastegate. it gets really hot behind the engine and this hose does not age well, it can split open and when the cycling valve opens your boost dumps out. let us know what you find.
