i'm tuning a 2000 silverado with a 227/232 588/590 113+3, 3600 yank, and 4.10 gears. i noticed in the WOT run log that the MAP won't go any higher than 70. my car hits 105 all day. Is there anything i need to look at, or is 70 max normal? There is a FLT 5 vacuum actuated trans on it too. It just doesn't seem right to me.

 

please post a log file...thats very odd.

 

Here ya go.

 

map hovers at 98-101 kpa in that log. Perfectly normal.

 

Know what, your right. Its the cylinder airmass in g/cyl histogram (spark advance) that i was looking at.

 

Glad it was something easy
