Would a tune be required? All I have are headers and full exhaust
I will run without issue no tune, but a big change in intake volume like the Halltech system provides will benefit from a good tune. Jim Halltech is well respected and states with a tune this intake will pick up 31HP.
I installed this intake on a 2010 Z and the customer told me within 50 miles of driving he could feel a SOTP difference, especially in the mid range (3400-4900). He moved to Florida and had in tuned there. No track times, but stated he ran a buddy with a 2011 that was stock and put 3 full car lengths on him from a 30mph roll after the intake/tune. Before they were about dead even.
General rule of thumb is 10HP is a car length (before/after same car). But there are a lot of variables in any given situation, so each car will respond differently and tuner skills vary as well.
I have the Halltech MF103 for my 2013 Grand Sport. It's pretty neat that it comes with the heat shield that separates the hot air from the engine compartment from the air intake. It seems like it's working really well. The car has the Halltech MF103 CAI, the LT's, X-pipe & full exhaust. It put down 435 LBFT TQ to the wheels w/those parts & a tune of course. I added the Halltech at the same time I got the headers & exhaust.

And is it necessary to keep the heat shield that it comes with installed?
The benefit of the shroud is to prevent warm or hot engine air entering into the engine through the air filter. Once intake air temperature (IAT) reaches 86* F, the ECM will start to pull timing, as much as 3* and pulls more timing as IAT's increase. All of which affects performance.
