Getting the waste gate set at 4 mm. Is pretty important, the car seams to run perfect at the setting. The easiest way to do this is the take the WGA out of the car and scribe a line on the arm while it's in it's natural position.(Scratch a line right against the body of the WGA) then install and turn the nut til you can measure 4mm from the body of the WGA to your scratch. The plugs will need to be gapped around .35 to .32. And don't be suprised that it will go thru more plugs now. If you start getting a hesitation under boost it'll probably be the plugs.
I have done the scribe thing and the 4 mm... But i think mine is going to run a little better with just one turn past 4 mm.... And last night i changed my pugs out to the new ones with a gap of 38 and love it! runs better then stock.
