- Turner Test pipe (good for at least 40hp with Evolve tune and not just all top end) - $400 + install
- Evolve Tune (great gain across the entire power curve) - $999
- Aftermarket Air Filter (proven for a few hp and considering it is cheap, why not... especially if you are running the stock charcoal filter the 08s and 09s came with) $150
- Power pully (cheap and proven power) $500

all that plus 4.10 rear and nitrous
