Recently picked up my car from Science of Speed and had some major upgrades done!
Engine related things:
Dyno graph:
Overall, I'm really happy with the results. To be honest, the car is scary fast now, and I have only taken it past 7000rpm once (i haven't driven it that much in the last 2 weeks). The acceleration feels like my Tesla P85, except a lot louder. The car drives great as a daily driver around town, and I haven't given a second thought to reliability.
Some misc notes:
One last note about Science of Speed: I think they are by far one of the best performance shops I've ever dealt with. I think the key here is that they actually respond to email/phone in a timely manner. They send out weekly updates and kept me in the loop of next steps. My car was there over Thanksgiving and Christmas, so it took a bit longer than usual, but they didn't rush it, and I didn't want them to either.
Engine related things:
- Stage 1 Engine Build - link
- SOS Twin Turbo
- AEM Infinity ECU
- E85 capable
- SOS Sport 350 Clutch
- SOS GT Spec Exhaust (the quieter one) w/ GESI Cats to handle the heat
- Standard maintenance: LMA conversion, new timing belt, etc.
Dyno graph:
- E85 (blue lines) = A little over 550hp/425ft lb.
- 91 (orange lines) = 480hp/390 ft lb.
- E85 provides ~70hp improvement
- Boost: 5psi by 2500rpm, full boost 4000 rpm

Some misc notes:
- I had a CTSC on before, and the twin turbo suits me better. Torque response is really good with the TT and I don't think the CTSC has much of an edge over the tt.
- The Sport 350 clutch is easy to use. Pedal is not much stiffer than stock, SOS says 10% over stock, it's probably a little more than that. Really drivable in traffic. They were able to rebuild my old Sport 275 clutch which for some reason felt very very stiff.
- GT-Spec exhaust note is deeper than the Comptech exhaust and slightly quieter. After a 6 hour drive to/from SOS, my ears hurt w/ the Comptech exhaust, with the GT-spec exhaust, my ears were fine.
- E85 is nice, I can fill up with any mix of 91/E85. E85 right now is 25% cheaper than 91.
- E85 hwy mileage = 22mph, 91 mpg 26mpg
- I had a 52mm GaugeArt gauge installed, it's really nice not having a plethora of gauges all over the place.
- Traction control is handled through the AEM Infinity unit now. SOS demo'd it for me and it works well. Previously with CTSC traction control was disabled because I had an AEM V1 before.
- AEM fuel pump is quieter than the walbro 255
- I think the engine bay is much cleaner now without the CTSC. It looks stock except for the blow off valve.
- May have to dial down the boost a bit
