6 SPD Manual
BootMod Stage 2 Tune
Wagner IC
Wagner DP
BMS Intake
ER Charge Pipe
VRSF Cat Back Exhaust
2022 Transmission & Differential Fluids Changed with Redline Oils

Previously after all mods I noticed that 1-2-3 gears no issues at all with boost and acceleration. 4-5-6 if going from idle speed to full throttle I would notice almost a bit of rumbling at low RPM or seemed like boost surging in the initial lower RPM.

Recently noticing that one 4-5-6 when I step on it I get a rev slip like condition that I have taken a video of. It only happens when going full throttle, does the initial slip once and then it's good throughout rest of the range but maybe sometimes feel a bit of a surge still through randomly throughout the rest of the range.

Looking to all you fellow owners for any advice or tips. This quick video I would go from cruise speed on 6th gear, step on it and after the slip I would do it again for demonstration purpose, I did not continue with the pull but I could do another video if it helps.

Linked youtube video I uploaded. Any help would be appreciated as this is driving me nuts, is it the clutch slipping, air-boost leak, etc?

Thank you,
Rui

I was thinking that as well, is it normal for it go to at 68K Miles /111K KMs? I never had this with any of my 200-300K cars before.

Any recommendations on replacement upgraded parts for a Stage 2 car? I'll have to start doing some research.

Thank you.
