That's a good sized cam that should give strong power under the curve. The chop will be pretty noticeable and you'll definitely need a solid driveability tune. No big deal for a pro, but perhaps beyond the scope of a first time tuner.

Thanks for the feedback Patrick. Forgive me for asking for this but, what do you mean by under the curve? I'm a noob to this stuff. Also, does efi allow for trans tuning?

He means area under the power curve (think dyno sheet).. Alot of people get bogged down on trying to reach the highest peak HP & TQ numbers they can. In reality it is best to have as flat of a curve as possible: meaning youre putting down good power throughout the RPM range instead of having to rev the engine to the moon to make reasonable power

For what its worth, torque curves by nature are 'flatter' than HP curves

basic example
