Risk of running too lean?
Hey all, I currently have the J's tsuchinoko intake, j's 60rs dual exhaust, and a test pipe. I'm considering purchasing the J's header as well but I've read that by running all of these mods together you run leaner than before. I was wondering if this could hurt the engine and also if I will be losing power by putting the header on in addition to the mods I already have. I'm not interested in using a VAFC or other fuel management at this point to rich the fuel out accordingly.
Bottom line, would it be a problem if I add a J's header to my current setup and would I notice any gains? Thanks in advance!

Once you add all your mods, why not go to the dyno (one with an A/F sensor) and find out for yourself if you're running lean? I'd do that for my own peace of mind.

I don't see any reason this set up will cause any damage. aren't you running OEM ECU?

seems to me that the ECU would adjust some for that too. The S2 runs so rich it "shouldn't" be a problem
