Is it just backing down the rpms while you sit there in park with your foot to the floor? That's what it looks like to me. How does it do when you put it in gear and actually drive it?

 

C-U-M-M-I-N-S

Is it stepping down RPM instead of a smooth decline to idle?

 

im not doin that myself...i rev it and let my foot completely off and stays up there...yes it does it while im driving, if i have to stop quick forget it it wants to keep goin....one time a friend of mine jumped in and mashed it to the rev lim thinking he was goin to make smoke..well he didnt and it got stuck up over 3000rpms for alteast 5 min before it came down

 

Ah Ha!! So it's holding the rpms up there when you let off. That is strange and mine sure doesn't do that. Go the the Diablosport website and ask the question on their forums.

 

Any codes? Does it do it with the truck returned to stock? I believe the throttle is electronic, so it could be something malfunctioning.

 

yea i havent gone on there site yet to post..no it doesnt do it when its in stock mode

 

5 minutes or 5 seconds?

Did you shut it down when that happened? Or how did you get it to "un-stick"?

 

Mine has hung up there in rpms two times if I remember correctly. Never in gear. And never for 5 minutes... it may feel like five minutes but it was only 2 or 3 seconds. I think we had this discussion on Diablo's forums already. I thought it was the extra pressure that brought about the hang up in higher r's but you said you're in performance tune which uses no pressure... I think... See these Diablo's are different from year to year on how they get their power. 03's-pre 04.5's add no timing on lower tunes but my 05' has timing on all tunes. Pressure may be different as well...

Now I'm confused...

 

yeah well it felt like 5 min but it def was 5 secs...it was in park i hit the brake, thought about it then hit the throttle little more..made it worse then in finally came down soo it was way over a min or 2...
