ok I am researching for my good neighbor on his 2001 crew cab 4x4 chevy... only mod so far is edge juice with attitude.. well, I have noticed his egts are pretty high and am pretty sure a new exhaust with cat delete would help this. My question is I have heard when you remove the cat on the truck it will sent a CEL and cause problems.. is there a fix for this as not having to invest into a diff program like efi live to eliminate this problem? while taking things out I have also heard a egr delete is good to do but will cause CEL also.. it's a california truck so it has all that good stuff on it. thanks for the help I appreciate it. I myself have a cummins. Diesel is the only way to go though.

yeah I was wondering why in stock configuration just using that attitude as a monitor his egs would get over 1250 crusing up a 2-3% grade not even getting into the throttle.. so I looked under truck and saw muffler and then looked closer to the turbo and saw the cat

from what he said when he got on it it was going higher so he just cruised it. He is going to get an exhaust so we will see what happens then if it throws codes we will have to fix it

ok the exhaust is on and no codes. we ended up putting a turbo back system from summit it was a pretty easy install and it sounds good. but when we went for a drive there was no difference in egt's but we added a cold air intake and it dropped the egts by 120 so it keeps it in the 1100 while cruising up a hill. I have not driven it yet to see what it does when the throttle is really used. but it's better than it was and sounds better too

yeah we did the same thing and it helped it sound better. I will have to let him know about the boost valve. not my truck so it's up to him... whats a good egt range for these? I have a cummins so it's a new ball game with the duramax
