well to answer ur first question MR = ''mitsubishi racing'' and the first things i did to mine was the basic intake and exhaust and boost controler well have fun with yours

 

yup me too...accelerate and life off gas...

 

While looking at the MR boost gauge. Another thing i noticed is that it usually "clicks" as its passing the 0 mark or very close to it. Any ideas???

 

lol the imfamous A pillar rattle in the STI

 

I have a click that sounds like it comes from the center of the dash, where it meets the windshield - perhaps the engine bay. It only does it once - right after I've reversed out of the driveway and driven it for the first time that day. My old lancer ralliart had the exact same click/tick - I'm assuming its just the mitsu goblins waking up for the day.
