greddy prospec BC not working??

[oddballmd]

just after a bit of advise on my greddy prospec boost controller. for some reason it keeps resetting this being the 2nd time now... ive re entered the low boost settings but it wont boost past 0.67 bar? last time it did this I just massively increased the Set and gain and it worked again.

also how do I stop this text field deleting letters I add? I can see that getting annoying

thanks
