I had Legacy dyno tuned at the Shop CT in Norwalk, CT

Cobb Down pipe, K&N filter and open source tuning. It raised the torque from 250 to 350, not much change in HP

This was done over 2 years ago. The battery has been disconnected a few times. Is it time for a new dynotune? Have there been many changes in open source tuning?

I run 93 octane only without the valet, 91 etc options which is fine.

When doing this I could add an up pipe. Does it add much? Can't afford a turbo back exhaust...

Any other bolt ons that make a big difference?

Advice appreciated

Since Bilsteins were designed for the spec B, coil overs are very expensive and Koni's require modification, Bilsteins seem to be the obvious choice unless money is no object.

My Bilstein/H&R combo takes some bumps a little rough, not certain if its just the harder ride. Bumpstops on the Bilsteins are internal

Modest drop, great handling improvement when combined with the Bilstein's.

The H&R's aare also cost effective, $228 shipped
