Fast Intentions exhaust and header comparison. Before and after UPRev tune (Dyno)

Another question off topic...

Do you know if the car made any more power with 100 octane ?

I have experimented with some from a local gas station by my house and other than the sweet smell I couldn't tell if it helped the car or not...

The car had a half of tank of 91 crap California gas. Then we dumped in 5 gallons of 100! Now in theory the car should take the extra timing you throw at it and hence pick up torque and power. We only did two runs and saw no change. However, my customer drove back to Vegas that evening which is about 300 miles. He told me the following day, he noticed a huge difference once he put some much needed miles on the car.

Back to the air intake issue. As of right now I am starting to feel like this car in it's current N/A stock form may be at it's limit as far as how much air it can take in. There is something going on with these heads and cams and this VVEL thing. Obviously if you change the cams, and port the ever living piss out of the heads you will pick up across the board. But until that happens you can only do so much with the bolt ons.

If I owned a 370Z right now, I would do:

-K&N drops ins
-Possibly an underdrive pulley
-FI LTH's (Of course)
-FI CBE W/18" Resonators & CF mufflers (Of course)
-Sway Bars
-Eibach Pro Kit
-4:10 rear end gears
-UpRev tune

This is just me speaking hypothetically!

Thanks, Tony
