So i just noticed a few weeks ago that my car seems to be lossing power. just doesn't seem like it used too. So today i took out my plugs to clean them (just replaced 2 months ago). Every plug was white, powdery. Would lead me to believe the cars runnin lean. I dont have a code for it tho. Over the winter i upgraded to Crane #14 cams, AEM cam gears, and Crower springs and retainers. Other mods are 55mm tb, Demon Coil, NGK plugs, and Pacesetter header and full exhaust. Anyone know what could possibly causing this lean problem if it is that?

Agreed. You are still under stock ECU control correct?

If you are on the stock ECU and upgraded to aftermarket cams, it is more likely that you would be running rich and not lean. Get yourself a datalogger, or at the very least a wideband, so you can see what is really going on.
What type of plugs are you running?

Nope. DSMlink is for 4g63 ONLY

If you just want a wideband to monitor AFR, any one will work fine. Personally, I used a Zt-2 datalogger and love it. It will log RPM, TPS, AFR, Boost/Vac, EGT, etc.
