I think the thread should have been titled "In-depth Tuning". Because i've always dreamed of being able to change compression ratios, drop in specific cams with different valve lift durations, adjusting timing, individual stroker kits randing even down 100cc increments, etc. A gearhead's dream.
Because let's face it, depending on how much money you put into an engine, it'll be producing serious power. I should be able to produce 1200 hp with an RB26 if i wanted to aswell. Although it'd be better if it were capped to a specific level for individual cars, as is in GT5. HOWEVER, as i've mentioned; in-depth tuning in combination with time invested into the tuning, and experience, oughta net you a very nice power result. For example, the 1000 hp mark should be very easy with something such as a Viper's massive 8-8.3L V10. HOWEVER, a 2JZ or an RB26. With those types of engines, you'd have to do a lot more tinkering in-game in the tuning menu to get extreme power results. To me, that would only be fair. And not to mention a HELL of a lot of fun. A 1200 hp Skyline GTR or MKIV Supra. Behaving as they should with such power. Rough idle, more difficult to drive in a conservative manner. But an absolute monstrosity once you open the throttle, and open up that car.
Would make me absolutely giddy to no end. That's my dream vision for GT's tuning. Purchasing a bunch of parts and saying "yeah, i got more power out of my car, D'UUUUH!" Isn't exactly the most fun thing to do. BUT , keep in mind, the in-depth tuning really pays off mainly with the lower displacing engines. Because of what i said earlier.
It would be beautiful.
