hi, if i had a stage 1 chip with a standard actuator what would my boost be limited to & would there be much of a difference changing to a -31 actuator?

Most people fit a -31 act with stg 1, the most boost ya can run is 1bar but thats at the limit of the 2bar map sensor 1bar atmospheric and 1 bar boost. After that ya need a 3bar map sensor and stage 2/3 chip to cover the fueling for the boost, also bigger inj s etc etc.

As said std actuator will not hold stage one boost.
Stg one a lot faster than std, well worth the money.

The reason i ask is it seems my car has a stage 1 chip but i dont think the actuator is any good, there are some photos in my other thread https://passionford.com/forum/viewtopic.php?t=304840
