Baker Tuning: 2009 370Z with GTM Stage 2 TT Turn Key

DIGItonium

Thanks!

The target was 6.5 PSI. At 3100, PSI was 4.8 and climbing to a max of 6.4 PSI at 5500-5900 RPM. AFR was around 12.2 at 3100 RPM, less than 12.0 at 3700 RPM, and hovered around 11.2-11.4 from 4100-7200 RPM cutoff. The requested tune was 91 octane (KS gas isn't so great).

It's a conservative setup for daily driving. So far I can easily break loose the "few months old" 305 Hankooks in 1st throughout the rev range when flooring it from a roll (VDC off). In fact, I had no idea the car was this easy to handle with the added power. For daily driving, I hardly get on it unless I'm getting on the freeway or making a quick turn to catch up with traffic. It's nice to get close to max boost at half throttle and be able to modulate it. Overall, it feels very good!

I'll give it a few months and continue to monitor the boost levels. Next year I will up the boost close to 8 PSI, but Sam says the wastegates are a pain to access. In that case, I will get a high quality manual boost controller over the EVC.

Therefore, Phase II will be put aside. So far there's no need to get an aftermarket radiator as coolant temps seem to be very stable even after a 10 hour drive. Oil temps seem to be well in control as well (peak at 215F), so there's no need for an aftermarket oil pan at the moment. If the car starts acting up in 52 days of 100+ deg. weather, then I will consider the upgrades. As much as I would love to get a GT-R intake plenum installed, there are other priorities now (i.e., house and settle down). So... it might end up in the FS section soon.

Stay tuned for comparison video and dyno video in about a week!
