It’s alive! Alive, I say!

We finished up the Werks Stage 1 turbo install over the holiday break.

Holy crap, this thing is fast.  HP Tuners is showing 23 PSI max manifold pressure, or around 8-9 PSI of boost (given ambient atmospheric pressure of 1 bar or 14.5 PSI). I had a CEL for a day and a half, but it’s since disappeared.

The (otherwise stock) car now spins the tires under WOT in second gear, at just about any RPM. HP Tuners shows a 0-60 time in the 5 second range, which is a huge improvement.

Fun part: when we started the car for the first time, it revved to redline for about 30 seconds, then almost died, then revved back up, then down, and eventually settled on a rough idle around 2k RPM. My best guess is this was the ECU trying to figure out how to deal with the larger fuel injectors. Of course, after reflashing the ECU with the tune I received from Performance Autowerks, it calmed down quite a bit.

There’s still some pretty bad hesitation when going from cruise to WOT, and I’m in the process of iterating the tune with Dave @ Performance Autowerks.

(BTW, Werks is a great company – very helpful, responsive and professional. I recommend getting your next toy from them.)

I’m planning on taking it up to the dyno in McKinney once the tune is a little more dialed in.
