i gout my IX MR a month ago. i'm not sure whether i'm just used to it now but i swear it pulled harder when i first got it. so lately, i've tried to watched the mitsu boost gauge while driving (not easy!) - it seems to peak at about 1.35 bar and taper to about 1.1/1.2. is this what you guys are seeing too?

p.s. this is on crappy 91 oct and at 5200 feet elevation.

 

do you see this reading in all the gears?? or what gear do you see this??

 

pretty consistent in all gears. peaks around 4k or 4.5k rpm i think.

 

Check your hoses for leaks and tighten the clamps real good. At high altitude you are going to be slower and yes the ECU will pull timing to prevent knocking with the crappy gas.
