Performance advice?

Seems fine. Looks good too!

Yeah with that kind of mileage it’s really good looking. I don’t really want to put a lot money into it so I’m just gonna do some cosmetic touches, lower it, new exhaust and maybe some headers and call it a day. I was gonna add a procharger to the list but decided not to.

Yep, seems normal.

If you want to SEEM like you're going faster, get a CAI and aftermarket muffler. No change in times, but SOUNDS faster.... Oh wait, never mid, you are in California. Truck mods are illegal...

Not a real accurate way of measuring. If you're serious about performance, buy a Dragy as mentioned above. Couple hundred dollars well spent.

I might take the truck to the drag strip for fun on weekends but it’s not a for sure thing but I’ll keep the dragy in mind.

A time slip would be good, if you go, post one up. Dragy is known to be pretty accurate compared against a time slip.

Does that engine still have the throttle body diffuser on the throttle plate? If it does remove it. Thats the first thing I do to any 4.3 or 5.0/5.7 vortec that still has them. Mainly helps with throttle response and not downshifting as much on the highway but I'm sure it helps a lot at WOT too.

Not exactly sure, I haven’t touched anything other than the spark plugs and air filter.

Thats the wide lip. My 99 Tahoe had that one. The one on my 97 van was 1/2 as wide. I remove them too. It does make a difference at WOT. My 383 has a BBK 80mm on it I found at the wrecking yard. $25 and it was like new.

If you're looking for faster 0-60 times, good tires, rear gearing, and a looser converter. These will deliver more performance than any other bolt on engine parts. Everyone wants to put on roller rockers, cold air intake, fancy air filters, headers, etc. but a converter with 2200-2600 stall and 4.10 gears will deliver way more acceleration than any of these.

I actually disagree. Air intake, headers and a tune did a hell of alot more than gears and converter. I then added a cam and 1.6 rockers. I gained over 100 hp at the tires.
