First off, yes it's a 2005 and yes I know I suck cause I have to have the Trifecta tune. Needed to that outta the way before people rag that. Okay, anyways. I'm working on building up my DD with parts each year. So far I have a LSJ exhaust manifold, LSJ downpipe with a high flow cat, 2.5 Tsudo cat-back, K&N Typhoon intake, 2.4 FE5 intake manifold and a 2.4 FE5 throttle body.

I got a tune for all of the parts on the car but for some reason whenever I press in my clutch pedal, the rpm will drop to 400/500 and then back up to 800. It'll also do it when I start the car. When I drive, everything runs fine and drives fine. Just does this when I press in the clutch pedal.

Now, besides that issue, next year I'm looking at doing a cam upgrade long with everything needed to go with said upgrade. What would be a good but decent cam. Thanks guys.

Im not sure if this is your issue but my buddys cavi had the same issue and we replaced the icm/coil pack and it fixed it.

Could also be a problem in the tune tho

If you have a lighter flywheel or heavier pressure plate & clutch it can do this.

The clutch to my knowledge is stock. Actually looked it over with a guy at work and he says it's a hose that keeps collapsing for the vacuum. So now I need to get a stronger wall hose.
