I finally get to have my truck tuned at Futral in a few weeks. I'll also be having my billet servo installed and my throttle-body ported & polished. I'm gonna try and get the money for some electric fans, so they can program them to come on at around 160*.

I know I will be having this done as far as tuning:

Idle raised from 500 to at least 800
Shift Points raised from 5200 to 5800-6000
Rev Limiter raised from 5200 to 6000-6100
EGR Delete
Maybe TQ Mngt Delete (not 100% sure yet)

Is there anything else I need done while I'm down there? Shouldn't I feel a big difference after tuning?

I plan on going back down after I get enough money for Eaton/4.10s and some heads that I'm fixing to get (used 5.3 heads-getting them Ported and Polished).

Thanks in advance

 

Do you already have some heads lined up for core or to take them to have done?

I have a spare set off of a 5.3 in my computer room/workshop/garage that I can part with.

 

Can they tune my GMS Mass Airflow Sensor or do I need to put my stock one back on? Can you even tune Mass Airflow Sensors?

 

With a 160 degree stat, these trucks run at 172 at the coolest. I'd set it at more like 180.
If you set them at 160, they probably won't ever turn off.

 

FWIW When I raised my idle, my driveline clunked ALL the time taking off. I turned it back down.
