It looks like...
 

You have the engine built to use more boost than an engine using stock compression, and internals.
Given that, I'm assuming you are running a higher boost than a stock internal engine can handle. [10-15psi, vs 6-8??] What is the max, you now run?
I'd suggest:
1. A progressive kit.
2. Turn it on at a low boost, such as Gametech suggests.. 6psi.
3. Ramp it up fairly fast, and see how the engine behaves, with knock. Too much alky will just make the performance poor. Tune the volume, and the ramp down for max, safe performance. I like a WB, and an egt meter, to "sneak up" on the tune.

Like I said, in my other post, call Julio @ ALKY Control, and get the nitty gritty details.

In the FWIW dept: We run the turbo BUICKS at 23#, on no led premium, and ALKY CONTROL Progressive. :devil:

Cool, thanks for the input Chuck.
I'm currently running the car @ 15psi. I'll use my WB and my HPT to dial it all in. I just needed a good point to adjust the pressure switch to turn it on...6-7psi sounds good in my book.
