A couple minor updates on my car.
The mild tune I installed a little while ago has been great. The most noticeable impact of the tune has been how the engine runs now. The tune seems to have smoothed out some of the wrinkles that appeared when the Cobalt morphed into a Goblin. Good stuff for sure. I am a street driver only, but I'd call my style "spirited" and thus far, I've topped out around 21 psi. Feeling pretty good about it and might offload the MPVI2 soon to recoup some costs. Maybe not though, I don't know yet.
Reworked my alignment recently. My rear tires were showing some uneven wear, so I put in a second set of camber bolts on each side and now both sides are really close to -.5 degrees. I also rechecked the toe in the back and I think I had some minor crabwalking going on. Fixed that (double, triple, quadruple checked with toe plates, etc) then redid the front alignment as well because redoing the back knocked my steering rack off-center. I think I am just going to find a shop willing to do a professional alignment, and be done with it.
Last but not least, I changed out my dash buttons and lighting to better match my current color scheme. I like it.
