First advice is use punctuation. You'll get a lot more responses when people can actually read your problem without having to stop and reread it.

As for the wiring, I can only guess they're talking about the 12v mod. You can find info on that on www.supraforums.com . We may have it here, but I haven't seen it.

Your 2j will run with a boost leak, and if it's big enough it won't build boost. It's easy to check for boost leaks also. Check all of your couplings to make sure they're tight. What turbo do you have on it? Is it stock twins? I'd check the wastegate also to make sure it's operating properly. Good luck and welcome to Supramania.

Holy fuk! i got a headache from trying to read that, What engine wiring did Titan use??? If it's running a MAF then it's a USDM supra (there plug & play from what i heard)
