Fat lot of good that will do. If you do not have a restrictor ring you can easily hit 1.4 bar.

 

You will just have to stay off the throttle and keep below 0.8.

As has been said, if it's fully decatted then the boost controller being disconnected is likely to do more damage than good due to boost creep. I've found that my controller on low boost keeps boost lower than when it's switched off.

do you think it would be best to keep the boost controller connected and try not to use high boost lol

Yes, and to not use full throttle... keep a close eye on what boost you are making as you accelerate.

 

Cheers,
