I just bought this iff Ebay http://cgi.ebay.com/ebaymotors/SALE-...QQcmdZViewItem Now after some reading im afraid that by switching from nozzle to plate I made the wrong choice. Most of the bad things I read about TB plates applied to LT1's. Are they a bad idea on LS1's. Biggest problems ive read about are leaning of first two cylinders. Should I keep it or return it.
