General Maintenance & Repairs - smoke at the dyno...

Just curious here ... When I got tuned this past weekend I noticed quite a bit of white smoke coming from the exhaust after about 6200RPM and little bit of black smoke after about 6500RPM is this normal? Granted the car has never seen this high RPMs before but the cam that I got raised the power band to 6800RPM... Also saw more white and black smoke on decleration but not as much. Car runs fine, Oil is good and Coolant is good, tuner said that some cars do this

Just curious as to what you all think

probably just clean all the carbon deposit

that's kinda what I was thinking

we see alot of fbodys do this

That's what I was told but it seemed like alot of smoke but oh well I guess

mine LS1 smoked also and i thought it turned out to be oil from the PCV in the intake
