I think your kind of limited to what the keydiver is set up for. If you had a real tuning solution you could push the limits of your turbo/engine. You really need a wideband o2.

I know I need a wideband so hopefully in a week or 2 I should've getting it. So I'm stuck at that psi meanwhile ?

You deffinately don't want to be running that much boost with only 91 octane especially seeing that you're bored 20 over. With that kind of compression you're taking the chance of having the engine knock. The best thing to do would be to run a higher octane before bumping up the boost, 93 octane would be a minimum.

Like others have stated your Chip is tuned for a certain tune/psi..If you go over that you might run into problems..I would invest in a wideband and dsmlink if you want to boost more that 21 psi..

Yea I know I'm pretty much maxing out my chip... I just got a wideband from a fellow Dsm tuner today.. And then after that Dsmlink v3 is next... A good tune n I'll go from there...thanx for the input
