    Colder plugs are going to foul unless you are beating on it. Probably could use stock heat range for break in

    Right make sense. Will the carbon burn off the plugs when i start hitting higher boost or am I better off swapping out the plugs later on? Because the way I see it, the higher boost will heat up the plugs again and burn off all that carbon. If thats not the case, i might have to get stock plugs until i hit higher boost, then get a new set of colder plugs.

    It should clean up once you start beating on it

    I was trying to figure out why my LTFT sits at -10 on idle. I thought maybe it has to do with the CAI hitting the top of the hood. Opened up the hood and the STFT shot up to bring the total fuel trims closer to 0! Ill have to figure out what exactly is pinching but I have a feeling the hood is pushing down the CAI and is pinching the inlet hose between the TIP and the turbo ... That 3.5 inch intake is a real PITA to get to fit right in the engine bay. Every time I try to push it down, the hose connecting the BPV looks like its going to fall off ... I might have to buy the JBR hose given how old and hard the current hose is.

    Its either that, or by opening the hood im letting colder air in bringing the fuel trims up (given its like -6 Celsius right now). In that case I have no idea whats causing this low fuel trims at idle ...

    Thanks, hopefully those plugs are going to clear up soon!
