Default problems... tune?

Heres the deal, I bought the car in my sig a few weeks ago. It had a idle problem. I thought it would be easier to start from scratch with a stock tune. That fixed the idle problem. I used efi live to adjust for the 3.42's and delete egr, and rear o2s ect...

My problem now is the car hits the limiter on the 2>3 shift, and from 4970rpm to 6k? I have constant 3.5* to 4* of knock.

I know for a fact I have to switch from the stock o2's to the bosch corvette 02's.

I only run 93 octane. I haven't really drove the car hard since I got it because I have been working on these issues.

I can e-mail my tune if anyone if they would like to see if i missed something

Any help would be greatly appreciated

Car has a FLP Level 3 trans with vacum modulation. Any tips for why it is hitting the limiter on the shifts? Line pressure is not controlled by the computer anymore so it should shift based of RPM, correct?

Correct. What are his shift RPM and mph set at for the 2-3 shift?
