Hey guys, I have a question on the rpms on my car, the thing is that when ever I raise the rpms to about 4-5k I let go of the accelerator and the rpms stay there for 4 seconds then start to fall slowly.
Any one that has had the same problem or that might know what it can be your help will be appreciated, Thanks



List of mods:
Hahn charge pipes
Stock intake air box with k nd n filter
Lsd
Catless downpipe
Hahn exhuast
Ko4 turbo stock one
Hahn I/C
Hahn canned tune

 

Based on your limited information it sounds normal. Nothing to worry about.

 

Alright thank you,

 

seriously? no its not normal.

 

jay list all ur mods on ur car and such. its not normal so don't listen to that guy

 

^^ I second that! lol

 

How high are you revving? If you go to redline and let off then I'd say that's normal.

 

I edited the post and listed the mods,thanks

No redline just 4 to 5 k. when I let go of the throttle it will stay at 4 k for about 3-4 seconds then slowly fall

 

That canned Hahn tune is a likely culprit. It's tough to say exactly though.

 

Are you running a blow off valve or vent to air BPV?

 

No blow off valve stock turbo just hahn charge pipes and stock air box

 

I thought he second a second not 4 seconds. I'm sorry I need to learn to read. RPMs hanging for 4 seconds definitely not normal. I thought maybe he was used to motors that downrev more quickly than the LNF a lot of people have asked in the past if it is normal for the LNF to take so long to downrev.
