Incorrect. We've seen gains on HR motor cars as high as 12hp on a totally stock setup. Other ones at less than 4hp. Tuning isn't about a raw number, every car is different and tuning allows you to gain a higher overall efficiency. The side effect of tuning is going to be power and fuel economy at the same time.
Edit:
Also no need to build these motors unless you're targeting over 600whp. GT Motorsports already has a kit on the market that is doing 550-600whp on a totally stock motor with 91 Octane California gas. These cars don't have a weak little VQ DE motor. The HR cars are doing 550 on the stock block, and the VHR is tested up to 600 with just a bolt on turbo kit.
