Got lucky a few weeks ago. I discovered my exhaust manifold was cracked a few weeks ago with only 24800 miles on the clock so I ordered a Z20LEH turbo unit. The problem is now that the queue for the company that I wanted to do the remap is huge and I'm not going to get it done before august. Is it safe to use the LEH turbo with a standard map? I have a boost gauge so I can check that the boost wont go over 0.7 bar or 10PSI which is the standard if I'm not mistaken.
