for a new person a .5814 RT is ok. If the tree is a .500 tree then you should release the clutch on the third light. If on a pro tree you should release the clutch when the yellows light up.

a 2.2 60ft is slow.... I think that perhaps you are bogging, and therefore not launching from as high as an RPM as you should. There are other factors to take into account and I'll ask that at the end.

your quarter mile time is high. I'd expect a 05 sti with a full exhaust including a header to be in the high 12's. your MPH also suggests this.

The real question:
If you have a rebuilt block (forged pistons) and a full exhaust, then why are you running such a relatively low boost pressure? I'd expect at least 18lbs. but with a built block your engine could handle 24 lbs (your turbo maybe not, but the block could) Maybe the header leak is preventing this?

So why are you so low? how are you recording it? Is it a bad gauge or a poor tune, or you just being very conservative.

I hope this helps.
So much false information here where do I begin. First off, bogging is not because he is not launching at a high enough rpm. He is bogging because he is dropping the clutch too fast.

Also, his mph which is 102 does not suggest a 12 second 1/4 mile time. Also, higher boost does not mean more power especially on the stock turbo. He should not be boosting 24 lb because this would not be efficient on his turbo.

Please don't post information that you are not sure of because you will mislead the community and you obviously don't know what you are talking about.
