| Chris Medaris was having a few issues: [ http://www.twinturbo.net/nissan/300zx/forums/technical/view/1122598/Why-does-my-tt-run-rough-cold-but-good-when-warned-up.html ] It turns out TXQ45 sold him a copy of an Ashspec tune for 550cc injectors. Chris has 370cc injectors. Oops. Glenn apparently has a habit of "harvesting" tunes from customer's ECU's, but is apparently too stupid to tell one from the other. Chris paid Glenn to drive up to Sherman to diagnose the problem because it was running so poorly he didn't feel comfortable driving it. He STILL didn't catch his mistake, and said he was fine to drive it as is (!!) I installed the proper tune from ztuner...all is well. He is lucky he didn't blow his engine from running so lean.
