Tune and upgrades.

Taking my 14 vert zl1 into local speed shop for "stage 1".
Here is the list of what they are doing. They said rwhp should see a gain of 60-70. Any thoughts or additional parts needed.

NGK tr6 spark plugs
160 thermostat
ID1050 fuel injectors
Port throttle body and supercharger snout
Mecto modular 2.5 upper pulley and hub, solid isolator coupler
CAI
Tune and dyno
