i have an 01 z06 with cam and heads and while going on the dyno it was blowing alot of smoke out the tailpipes we figure its the rings giving out but the car only has 10000 miles on it 4 of which are from me. also while on the dyno the car dopped 35hp at about 5500rpm and then shot up at around 5800 and leveled back out. any ideas as to the problem would be much apreciated!

 

What color smoke??

 

how good is the tune? Post a dyno sheet and vid

 

check valve seals

 

ya the smoke is a grayish, the guy who tunes it is pretty good, so idk

 

Sounds fat.... I.E. "rich"

 

no a/f is 12.98-1 its not fat but it looks like it

 

Did it puke smoke the whole time..... Or just when it had the "anomoly" that you mentioned?
