Uh yeah lol. Tuning for boost will definitely be tricky since the 3400 never had a factory option tune that added support for a 2 bar or higher MAP sensor like the 2.4L did. You'd have to use a 2 bar sensor and scale the values in the PCM to pretend, which works, you just lose resolution.

Could be, I can scan it with HP Tuners and see if it reports any errors that don't cause the SES light but are still visible to a scan tool. Also for the cost of the credits we can read and edit the PCM and make sure none of the fun codes ever report errors. Shhhh....

Nice. Yeah 310s are for baby level boost.
Anyways....
I ordered GT3076R.
