It's been a bit since I've had a Northstar, but I remember there being something like an AJ tune or something to that effect (though I also heard they weren't all that perfect either). I personally wouldn't do it, but maybe someone knows more about that than I do.

Although it's offtopic, there was/is a guy with a '99 Seville STS that turboed his Northstar and was running 11's (albeit, he dropped probably 10 grand into the whole job, including custom work and tuning (he used an LSx computer...I think). So yeah, it's possible, but nowhere near easy, very expensive, and requiring lots of custom work. So unless you're bull-headed or deeply set on it, I wouldn't consider turboing your Northstar as it is set up in your Bonneville.

There is no aftermarket support for the 04-05 Northstars. HP Tuners only supports 06 and up Northstars.

I would love to find out that I am wrong about this!

Adding an STS rear-mount turbo would be a reasonable solution, with some fabrication required. But since you can't tune the PCM, you are going to need to go to a standalone.

Nitrous is the only affordable way I can think of to take on that GTO in your Bonne GXP.
