Sounds like a gimmick. There's pretty standard paths to take for upgrading 3800 Series 2 & 3 cars.
As I mentioned yesterday to the member asking about GP GT upgrades, watch ZZPerformance's YouTube videos on first mods to add.
N/A: you can add a handful of upgrades listed in my post yesterday, and see 20-30hp across the whole range, but even a full heads/cam build would be limited to reaching performance of a bone stock Supercharged car, or barely better.
Supercharged: Mild bolt-ons and proper tuning/scanning can reach 13-sec 1/4mi times without much headache, then you need to decide if spending money and effort to buy/dial-in a cam upgrade is worth it. Intercooler and fueling upgrades are a big cost that benefit the setups well, and can start getting too 300-350whp and 12-sec times, creeping into 11's with more effort. The typical limit of the M90 is about 400whp with the biggest cam and ported heads setup you can buy, which can get expensive to see potential for mid-11's runs.
Turbo: high initial cost, but big gains when properly set-up. Bolting these on a regular 3800 can get you to 300-400 whp with careful monitoring. Swapping from a supercharger to turbo setup provides the lower compression to run more boost, and intercooling is an inexpensive necessity either way to maximize power. Getting past 400whp and into the 11-sec range can happen without a cam upgrade, but doing one will add even more potential to flow the air properly and open up the possibility for 500+hp and 11-sec or better in a daily driven pump gas setup, but it'll cost a bit.
