Just got my truck back last night from being tuned .. I notice I have no engine brake, when I let up on the gas pedal the still slowly climbs up. idle at about 800 to 900 range.. To high ? right! My first Supercharger So help me out Please! Thanks Rick.

 

Th still slowly climbs too high? What does that mean? Sounds like he turned off DFCO which is what cuts fuel under hard decel.

800 rpm is fine depending on the cam and motor. Rest of the specs?

 

Its stock other than headers... It means it doesn't slow when you take your foot off the gas pedal, its still go's at the same speed and then slowly speeds up.

 

Your tune is off. Simple as that. Those DBC trucks are harder to tune. I've had my fair share of trouble with them at idle. I'm inexperienced is what ot really comes down to.

 

Does it do that when moving or only at idle?

 

I was thinking he is was good. SQC tuning, Professional Service? Well he email me a new tune. And I'm suppose to put it on? This is what 600.00 gets.. And he used my credits or it would have been 700.00

It will take off on its own power and if I would let it, maybe see a 100mph in a few miles down the road I'm sure.

 

What does the throttle position sensor read with the throttle closed? Post a log so we can look.

 

I have a Hp tuner. But do know how to really used it just yet.

 

Im guessing you email him logs you save from the scanner? Attach one of those to a post here.
