i have a 5.3, but can only find TAC modules for 5.7's

TAC modules have to match up to the year range of the PCM AND the throttle body.

03-05 TAC module works with 03-05 truck TB and 03-05 PCM (BLUE/GREEN connectors)

01-02 TAC module works with 01-02 truck TB, 97-04 Vette TB, and 01-02 PCM (BLUE/RED connectors).

03-05 TAC modules have an aluminum mounting base, 01-02 TAC modules are all black plastic including the mounting base.

I hate to hijack this thread but this might be pertinent.

John,

Will the 90mm LS2 TB work with the 03-05 truck TAC module and PCM?

The 90mm LS2 TB is unique and will work with the 03-05 PCM, but requires switching to the 01-02 TAC module. It also requires our adapter harness for $50.

Will the 03-05 truck pedal still work or will it need to be 01-02 as well?

The 03-05 truck pedal works.

will the TAC module work on a 5.3 if it came out of a 4.8L?? I got a tac module and pedal from the junkyard but afterwards i found out it came from a 4.8L truck??

That will work fine as long as it follows in the correct year breakdown described above.
