Hey gang. Ive had the Stage 2 kit on my car for about 2 weeks now. At first car pulled hard thru all the gears, but now I am losing power (especially noticable in 2nd.) It feels like the car is bogging down. Im not getting consistent power up to redline. Kinda stutters, and once almost stalled out on me.

Ive researched a bit and all I can think of is that perhaps a clogged cat, may be my issue. Truly I do not know. Belt slipping? Reflash for the kit wasnt done properly? Perhaps a colder step plug?

Im not throwing a cel either. Any thoughts on what I can look for to narrow down the options would be appreciated. On my way home, ill test how fast im building my boost, and will check my plugs, but otherwise I called my dealer. When you hit it in 2nd gear, you cannot miss it.

Thanks

 

are you hearing a whistle when you start to build boost?

 

My stage 2 kit is runnin good and i drive spiritly, i doubt the belt is slipping, i changed the spark plugs to the ngkbkr7e's, but even before that it was fine, do you have an intake you just put on, my car was doin the same thing with my new intake, i disconnected the battery for 30 min and now shes fine.

 

Somewhat. Ill listen harder on the way home.

I had the intake on before the kit, perhaps I need to try unplugging the battery again if thats the case.

 

Mine did that a couple days after I got a 3" pulley and spark plugs. It went away and has been fine for months now.
