I have an 03 sierra currently running a torque rush (X link) harness to a stock L92 throttle body of a GMT900. The throttle response seems somewhat slow. Is there a way to improve this, either by changing something in HPtuners or by swapping out the throttle body?
Thanks

 

Have you had it tuned?

 

Atomic may know this, but iv heard you can adjust the sensitivity on them. Personally I would want it tuned to act just like a mtb, just what I'm used to

 

There is a warning in hptuners about that saying it may brick the pcm. I wouldnt suggest trying it.

 

Yep, and people have changed it and bricked the PCM so there is truth to that. I have found different OS's have different values in this table, I accidentally ran a modified table once ( was factory table from another OS) and if did affect TB sensitivity, but once I realized it I changed it back. Mine is plenty sensitive with the factory table and LS3 TB as some have seen from the TB video I have posted.

 

Is the LS3 tb any different than my L92? I was wondering if changing to an LS3 or LS7 would improve the response?

 

Is it a factory safety setting and the pcm detects it has been modified and bricks itself. I've heard of it but anyone know how it actually commits suicide.

 

The sensor(pedal) and the throttle body needs to have specific calibrations to work together properly. Even if you don't brick the PCM when you change those values, you'll likely have problems afterwards with going into limp.

Like others said, avoid changing those tables.

A tune will definitely help with your throttle response.
