Hey every body, My name is matt and I'm new to land cruisers but iv had a few Tacoma's over the years. Thanks for letting me a part of 1H8MUD! So I just got a 2000 lc for the wife, 180k on the dash and it runs great but we both feel that its down on power having the 4.7 and 4.30's. I am a mechanic and to me I thought it felt like an exhaust restriction. I'm getting 4-6 psi of pack pressure on both banks checking at the up stream o2's. (engine cold in park wide open snaps) I know that's a high reading but the cats on this are huge. so I guess I'm looking to know if any one has any insight or maybe knows what a healthy back pressure reading is on one of theses trucks... Thanks a lot.
