Funny that I drove that car for about 3 months and never added a drop of oil. I drove from LA to Tucson w/o needing a drop of oil. My car ran like shit the whole way home. I called Greg and asked if I could get my Z1 chip back and a refund and he said NO. I did not get a full run, not because of the oil. Remember???????? Guess not. I was trying to get my cheap boost controller adjusted and got two attempts, then kicked off the dyno after a small amount of oil came out of the front of the oil pump. I did not need to add oil. The oil pump is replaced and their is nothing wrong at all with my Z. It it running exactly like it should now....After I put in a new Z1 chip. Greg never offered my Z1 chip back or a refund, and admits I did not get a full tune. Just charged for one. My Z was knocking like hell when I left SZ. He acts like I live next door. I can't even find time off work for a local shop visit, but they act like it's no big deal to drive 14 total hours and spend 500 bucks, just to be told to do it again. Why did I not get my old, good chip back? I called b4 I was out of LA voicing my concerns. He just wants to blame me. So go ahead. Make things up about me if you want. I don't care.
