Low on power?

Pull your plugs they dont lie.

Is your CEL on?

Nope

As mentioned, confirm the fuel pressure before jumping to a dozen other conclusions. Starting from the top.

Why do you have a C&L 76mm. Did you change the injector size?

The best spark plugs are plain and cheap copper core. Rare earth metals are not the answer.

The IAC should control the idle as the load changes when at idle such as the AC coming on or shifting into gear from Park or neutral. The IAC has no performance affect at speed.

Factory idle for an auto is commanded by the ECU to be 700 rpm. Your idle is correct.

A TC issue will be one of it slipping or shuddering especially on the 3-OD shift. There is nothing to indicate that it's an issue.

Don't mess with the IAC air bleed screw. It's just for ultra fine tuning of idle quality. Your idle issue points to the IAC.

Have you pulled trouble codes and if not why not. You need to know what the ECU is logging. You DO NOT need to see a CEL for trouble codes to be present.

The 76mm maf came with the cai, calibrated for stock injectors. I'll get to auto zone or pep boys to have them run a test for codes

1. Check codes.
2. Swap for the stock MAF. See if runs better.

You really don't have many mods, and 50K miles is nothin'. You may have a O2 sensor or something simple going on.

I'll see about doing that
