Greetings there,
I have a 2006 mcs ( 16+2 , grs cooler, alta cai, one ball, wossner pistons)
I see a problem with my boost readings. The boost numbers are increasing until 6.400 rpm to 1.10bar and then decreasing to 1 bar till close to the reds.. Is that normal i mean i was used to the boost constantly increasing.. What should i check? Map sensors maybe?
Thanks a lot for any help!
George

 

Sounds like a boost leak or belt slipping. IC couplers are known to fail...belt tensioner is known to fail...belts stretch. First thig I'd do is take a look at your tensioner and see how many holes are visible.

 

Thanks a lot for the quick reply! By belt tensioner you meann the thing that stretches the pulley belt?

 

Yup. Thats the tensioner.
