Yeah man. Road car aero with something like this at road car speeds, even at the track, just not going to make a difference. May change a MPG here or there over thousands of miles. Maybe. In my opinion.
I think the only truly economical, sensible, and objective option to answer this question is for @zrk to do some runs with and without the wind buffeting things on to see if it impacts performance at the strip.
Today I mentally prepared for my wife to shit the bed when a 2nd CF spoiler shows up tomorrow when I haven't installed the 1st one I bought. She doesn't care about the money, it's the fact that the other one is still sitting in the guest bedroom... next to the Verus hood louvers that still...
Yeah for sure. I've always used it more for things like my truck, which has a 93 tune on it, that gets taken to places that don't have 93 and I need to use it in a pinch on occasion.
I can vouch for the product (it's a quality piece of kit), and while you have one person's opinion, the change to me felt more than just minimal. But I have zero data to back that up, so take it for what you will.
I can't comment on E85/35/50/etc. in this car, though there's plenty of evidence out there, but I will say that I've had positive results from properly measured Boostane Professional additive to fuel in other performance cars. I have two cans sitting in the garage I've been considering properly...
Nice! Someone with more experience than me tuning a car with an aftermarket downpipe will have to chime in, but I will say, an aftermarket downpipe running a stock tune/ECU/no piggy back made a big difference for me. Again, based on the butt dyno. Highly recommend it if you're looking for some...
Not much at all in the form of engine modifications that would make a huge difference in terms of a custom map - AA catted downpipe and an AWE Track Edition exhaust. I believe the HKS air filter and FTP turbo inlet pipe have zero impact, but who knows. The difference here is that the custom map...
I just went through the process of creating a custom 93 octane map with @Jesse DaBears, and going from OTS map 2 to the custom map 6 was like night and day. Much smoother and the car pulls harder, based on the butt dyno. Next up, an E35 map! His services are highly recommended!
