1- After getting the tunes, you are welcome to submit any data logs for us to review and see what extra we can get out of the fuel.
2- We only work with the nGauge. If you go into the COBB product page, you will see it cannot be added to the cart.
3- An intercooler will help with consistency. Ecoboost trucks are robbed of power due to heat soak. An aftermarket intercooler and lower temperature thermostat will combat that. Thus, keeping your power level stable. The key modifications to gain power are tuning, water methanol injection, aftermarket turbos, nitrous, and higher octane fuel. Intakes can help with acceleration, but will not increase top end power.
4- We do not have one intake that stands out above the rest, but if you are looking to go off road a lot with your truck, it would be better to get a closed one like an S&B. It won't be as loud as an open one, but it should keep more of the debris out.
