Throttle Boost setting question

[xgto]

If the canned Trinity tune 91 or 93 already have 15% throttle boost per set, then when you go into modify the throttle boost, is what ever level you increase too is that starting from 15% already? If you set it at 20% does that ,mean that you are really at 35% ? Hope this is not to dumb a question!

Correct

Garrett, so to clarify - I'm set at 20% boost but really at 35%

[garrett]

Yes. you are adding to what has already been adjusted

Is it safe Garrett? What would be the highest you would recommend, or is up to how I want the truck to perform?
