Went to Cobb SoCal last Friday for my tune. I work nights, so I headed out right after work, thinking that I could catch a bit of sleep while they were installing all my parts. Wouldn't you know though, I couldn't sleep at all!
It took them a few hours to install the DP and Intake. They have a "dyno cam" in the waiting room, so I got to watch as they pulled my car onto the dyno and strapped it down. I was tired, but excited to watch it happen. Before the first run, it looked like to me that one of the straps on the front wasn't tight, but I figured they were professionals. As he started the first run the car suddenly pulled to the right. I nearly **** my pants! Turns out I was right, and it wasn't strapped down tight enough. No worries though, the car was fine and I watched him strap it down properly.
Watching the tune was pretty cool. I could see the graph and gauges in real time. It was especially awesome watching my car making more and more power.
In the end it made 292 awhp and 330 ft-lbs, which is more than I expected. To show the difference between a pro tune and OTS tune, he flashed the OTS stage 2 map and did a pull. Car developed 267 awhp and 305 ft-lbs.
The best part is how much smoother the car feels. The power delivery is much better, without all the dips I could feel before. Plus the intake noise is fun. So far my mileage has suffered quite a bit, but that probably has more to do with my foot than anything else.
I'm having a few issues with my AP. For some reason I can only get it to display one metric, A/F learning. No matter how many gauges I tell it to display, it just shows A/F learning... It's probably me though, I need to play with it more when I have some free time.
Overall, I'm very pleased with everything. I've already taken it on Mulholland Drive and a mountain road to Palm Springs. Can't get the smile off my face.
