For the big Lambos, there's nothing better. They look mean anyway, so black gives them a more menacing look. When we repaint, I'm thinking I'll go matte black instead of gloss and paint the calipers green, as something different. I was a little surprised by how wide it is, it's crazy.
Dyno tuning. What is it? How does it help you? Primarily, "it's to squeeze as much performance out of you car as possible", that's what "tuners" will tell you, but that's wrong. It's to get as much reliable performance as possible, within the environment and method you plan on driving. This is tough and not all tunes are right for all drivers and situations, even those from the factory. Today things were a little slow, so I stole one of the garage staff (the owner) and we spent the day tuning my forced induction cars, using our new EZ-Tune/Flash system. The Ferrari 458 (new Heffner TT system installed), McLaren 12C, and Acura NSX (w/ LoveFab Stage3), we'll get the rest of them later. The results were all surprising, and shocking in one instance.
The NSX didn't seem to be tuned properly at all, or at least the boost wasn't regulated for the expected fuel/air rates. Once we compensated for altitude, specified octane, and boost levels, we made 610whp at full boost, which is 40 more. Also it isn't running as lean, meaning it'll get better economy at be less likely to cause pre-ignition (pinging). The fully variable boost setup was causing problems too, so we disabled that and now have 3 presets; 5 (road), 12 (sport), and 25psi (track), and locked out air/fuel adjustments.
Next up was the 12C, and this was the shocker, McLaren's settings were conservative. That's not surprising, but the extent of the conservatism left us baffled (likely economy reasons, and not wanting to be as competitive with their upcoming P1). They claim 17.4psi, but the reading is barely 16, and the turbos and cooling system can easily handle 22 (25 as long as you don't live in a desert). Octane doesn't even become a factor until you reach 25, over that you'd need >93oct. FYI, that's what we figure the P1 will have, a bored and stroked 3.8 V8 (~4.5L) @25psi, which will make around 850bhp. So we jacked the firmware (don't ask), set it to 22lbs, and adjusted A/F. Stock is 618bhp but now it makes more than at the wheels, 637. Without losing much in the way of low-end torque. Crazy!
The difference is noticeable.
Finally, the 458, which came with a stock tune on the replacement ECU. Same story, the stock setting was at 5psi from the small turbos, but they're quite capable of 7, and with the modded intercooler that my mechanic fashioned and wastegate adjustment, it handles it perfectly, even on pump gas. 893bhp & 782whp, that's 331hp over stock. Then... we set it back to 5lbs, since we're not sure how much power the transmission and differential can take. Time for more research. I wonder if Ferrari would just volunteer the info. I didn't think so either.
