Pulley down all the way to max out the blower (in fact overspinning it isn't a problem) and add meth which will allow more timing. Very good bang for your buck.

or do i gain more power with 10 psi and e85?

If e85 is available to you I'd run that, up the boost, and add one of our blower cams.

Feel free to contact us and we can go over a few options.
