Speed density LS3 tune?
Speed density LS3 tune? I sold my last 08 C6 for a few reasons but mainly it was tuned by 3 different tuners and the slight surge would never get resolved.
Now I am about to buy another 08 with the G6X3 and bolt ons and obviously it surges as well, after 2 trips to his tuner. The LS3 maf's are WAY sensitive so I am curious-
Has anyone speed density tuned an LS3 yet?

Jay, I would advise that no amount of tuning is going to make you happy with another big cammed set up like that...might be time to look into a nice set of heads and a more mild cam combo.
I would actually go smaller with the cam but since the car is modded already, thought I'd ask.

I've found the credit card MAFs to be much more sensitive than the screened MAFs of the earlier C6s. Speed Density tune will help a lot, but most surging is a result of timing jumping around and airflow not being right for that particular rpm. You'd be amazed how much magic can be found with proper airflow and timing. Speed Density just tops it off!
