2010 7AT Uprev Tuned @ Stillen - 10.22.10

Fly1 Motorsports

Hey Guys,

As the title says, I got my Z Uprev tuned by Aaron @ Stillen today on their Dynojet. They were my third choice after Technosquare and HB Speed - but became my first choice quickly. I tried getting an appointment w/ Technosquare for a few weeks, but after being given the run around and dealing w/ the rudest receptionist of all time - I decided to take my business elsewhere. I tried contacting HB Speed, but apparently they were bought out by COBB...and are retrofitting the shop to become COBB Socal. Thus, I booked an appointment at Stillen as they're only 10 minutes from my house; and were reasonably priced ($550).

The performance mods on my 7AT are just some basic bolt-ons:

-F.I. TDX CBE 18" resonated CF mufflers
-F.I. Resonated HFCs
-Injen CAI

As I'm in SoCal, I was limited to 91 octane (Shell V-Power pump gas). Weather was low 70s and a bit humid (was drizzling earlier in the day).

Overall gains (pretty consistent through the RPM Band):

+8.87 HP
+9.66 TQ

A/F Ratio was running pretty lean (13.7) on the first run, so Aaron brought that down to just under 13 to be in a safer range. I would have loved to have gained 15+ HP, but all things considered, I'm happy with the gains. As you can see from the chart below, Stillen's Dynojet runs a bit more conservative than others out there.

All in all, a good day w/ the 370!
