Ed tuned my car yesterday and everything went 100% awesome. I'll just give a quick account of it here. We started tuning around 3:30pm and the temps were in the low 90's for most of the tune. We did a baseline and since my advanced multiplier was only at 7, the car was weak. (I don't remember the HP, but Ed said, it rivaled stock). I didn't think my car seemed much faster after the UP, DP, and CBE installs. Perhaps my car didn't like the free flowing exhaust. Ed quickly fixed all that.

After he loaded a baseline he had created, the car felt like a whole new beast. After 3.5 hours of tweaking and perfecting, I was at 206 WHP and 208 Ft/Lbs IIRC. I think it was a 40 whp improvement from baseline IIRC. The real cool thing is that Ed kept saying he couldn't believe how great my boost response was. After a shift, the boost needle would swing violently and stop on a dime at 17psi. I guess most WRX solenoids are weak and people have been replacing them with an inexpensive GM solenoid. He mentioned that he really prefers divorced wastegate DP's (like mine) as it makes it so much easier to tune the boost maps. He had never tuned a car with Crucial pipes and we were both impressed at how much they helped spool up. I was so stoked at how my car's responsiveness and power were improved upon, and the attention to detail Ed exercised.

As far as danger goes, we only did around 10 3rd gear pulls to redline and checked for boost spiking in 4th. I don't think I was ever asked to exceed 95, but I did anyway because I had never felt 4th and 5th pull so hard and I was stoked. He warned me not to "load up" 5th at low RPM's, and it was better to downshift. I agreed, but man, I could have cruised all the way up 80 in 5th if I had wanted and accelerated too. This is nothing like my old car.

We also went from a stop to the top of 3rd a couple times. At no time did I feel that anybody was in significant danger. Traffic was scarce and if there was a car or a bicylce (once) we wouldn't speed past them. There were no cross steets or driveways or crosswalks or blindspots or anything on the "dyno" portions of the road. I am no longer as sceptical of the danger factor. I actually got passed while driving around 55 between pulls a few times. Most cars just jam down these roads.

For reference, here's my mod list:

03 WRX:

Borla Hush CBE, Crucial UP & DP, K&N Drop-In, Heat Wrapped Stock Headers, Intake Silencer Delete, Omori Boost & EGT Gauges mounted in an Autometer 52mm Bezel Pod, Gun Metal Rota Torque 17's, Yoko AVS ES100's, Eibach Pro Kit Springs, KYB AGX Struts, Fumoto Oil Drain Valve, Rock Blocker Clear Bra, Mr. Josh's Solid Endlinks, and an '02 Sedan Rear Anti-Sway Bar. Protuned by Equilibrium Tuning.
