When I left work at lunch I hit the throttle and bring it up through the rpms I saw 8-9 lbs boost, after I eat I'm heading back and do the same thing but only see 5-6 lbs boost could it be my belt slipping once it gets warm?.....

 

Did you put the new gates belt on ? My gates seems like it tightens up after its warmed up . When I went to the 3.12 pulley I tried to put on a smaller belt . I tried and almost got it on .So I thought maybe if I warmed the belt up , it would be more plyable . I was wrong...put it in the oven for about 10 minutes....took it back out and tried again . It wasnt even close to going on this time . ......Bill

 

No I used the one that came with the 8 lb pulley, I did notice the tensioner is maxxed out so I guess I will pick up a new smaller belt tomorrow, on a side note: My tuner is emailing my map tomorrow...finally.....

 

Problem solved with new belt and tightening the sh%t out of it
