Rev bouncing at 3.5k rpm

[SKELE]

I was reving the car in first white clutch in and parking break on and I was bouncing of 3.5k rpm. I was wondering if anybody knew if this was some kind of launch control mod or other problem.
I bought the car modded from a dealership but the original owner didn’t provide a list of the mods.

What do you mean bouncing off? You had your foot in it and no matter how much you pressed the accelerator it wouldn't rev past 3500?
And you had first gear selected but held the clutch in to rev the engine?
I would not recommend doing that. I would not recommend holding the clutch pedal down at all. Just use the clutch to start off and to change gears. Otherwise when stopped put the transmission in neutral. You'll thank me when you don't have to replace the slave cylinder because the clutch pedal sticks down.

There is no launch control, and there should be no rev limiter at 3500.

If he has a tune it's quite possible, my Dizzy tune has launch control at 2.5k if clutch is held in and the pedal is stabbed

My first thought was you are describing launch control. You almost certainly have a tune.

This is exactly how Cobb describes their launch control behavior: https://cobbtuning.atlassian.net/wi...eatures+Using+Launch+Control+on+Ford+Vehicles
