Any point to a tune without a CAI?
#24
Go look at my FRPP tune thread. You can see what just a K&N and tune does on a dyno. You notice it for sure.
Going to a true CAI, improving the flow, and adding a tune for that goes one step further. All depends on what you want.

An aftermarket cold air box will take it one step further, as Overboost mentioned. However you have to choose a system that will flow significantly more than stock. If it does not require a tune, its not giving you much over the stock airbox.
Once you have a system that requires a retune, compared to the stock airbox your gains will be small below 4,000rpm, but a good airbox will take off from there and make more power all the way to 7,000. So there is good usable power there.

Or is it at the throttle body and intake manifold? Seems to me those are the restrictions regardless how large the intake tube is.

Yeah I would like to just see a dyno with the stock air box and tune, and one of the cai and tune. I would think the cai would make a bit more top end power but not much. I think as stated that the 93 tunes would yeild around 70% of the results. But I would like some dyno numbers to back that up.

Theres plenty of data out there.

You cant compare dyno's from different cars/days. Do a search for the tests that have been done that are the same car/day/dyno and only look at the before and after gains. Don't concentrate on whether one guy made 390 stock vs 370 stock on different cars/days/dynos. All you will do is confuse yourself.

Our auto CAI/tune only packages are anywhere between 370-385 depending on vehicle, gear ratio, dyno, correction factor, octane, etc. Manual vehicles are seeing about 5-7% above that. In the 400 range, depending again on vehicle, gear ratio, dyno, correction factor, octane, etc. Pretty consistent results throughout most of the top tuning vendors as far as horsepower/torque per combination.

That, throttle response, variable cam timing, shift points and firmness, etc. That's where you get that night/day difference in driveability.
