Default Map sensor reading high at idle

So my car was idling at around 29-30 kpa but last night while driving it started to idle at around 45kpa and when i gave it low throttle it would drop down to around the 30's then go up. I thought the map line might be kinked but its not.. Anyone?

Bump. Vacuum leak maybe? Ugh if I fix this last thing I can take it to the dyno!

What rpm is the idle at? 45 is definitely an error, at 45 you should be at 5-6k rpm unless you got some serious loads on your engine. Whats the map say when the engine is off?

Well that doesn't make any sense.. part throttle is less than idle?

Thats exactly whats tripping me out!

Edit: Turned out to be a leaky boost gauge. Dont use Ebay boost gauges!
