He wants to sell you a kit! He was no experiance with the crossfire. Jut get it done with the shot 75 and record the dynos with fuel/air ratios to send to the tuner. Pick a tuner and get a custom dyno. Its the right thing to do. I would get the injectors upgraded and run some NGK spark plugs too. Consider that if you want a CAI later, than you're going to have the elbow drilled twice. Just pace yourself and you won't do things twice.
