Procede question: What would the stage 1 UT value be to mimic stock?

Want to put one of the two maps to be similar to stock power. I think I just have to adjust the UT value, right? If so, to what?

Why not just enable Valet mode so your car starts up in stock power......

~10%. This will give you stock like boost while retaining all the CAN features. Otherwise just use valet mode.

+1. 10% will be slightly more powerful than stock. But pretty close (within 15whp I'd say).

Thanks. I take it the UT only works in increments of 10%? 1% wouldn't work?

You can go in 1% increments. But 10% is the lower limit.

Hi Shiv, you might want to correct the user documentation then on your site HERE.

It says it can go down to 0%:

User Torque Map

This parameter defines the maximum boost level of any given map. At 0%, the tuning features are essentially disabled and performance will run at stock-like boost levels. At 100%, maximum theoretical performance gains are induced and boost pressures will be maximized. We suggest leaving the default value alone which will vary depending upon map file stage selection. Running too high of a User Torque level on pump gas can result in poor performance and, at worse, possible engine damage. 0-100%
