My car is mostly stock but I thought I'd make a post about my progress with the few things I've done and their purpose. - TracKey (purpose: performance) : This is pretty obvious. I have read plenty of articles about the development of the track key with numbers ranging from 200 to 400 parameters in the PCM being changed, including throttle response, torque management, intake and exhaust variable cam timing, ignition timing, among others. It also automatically sets the steering weight to heavy (adjustable with the regular key) and relaxes stability control safety nets. I feel like ABS is also less intrusive/aggressive but have never read about that so could just be in my head. The intent was to tune the engine to run like the Boss 302S race car, dialed back only for street durability requirements and emissions. - Ford Racing Torsen Diff - OEM spec (purpose: performance) : I bought my car used (with 231 miles, mind you). It's a long story but the point is, I didn
A couple of weeks ago, I posted my first impressions of Michelin's PSS vs Firestone Firehawk Indy 500 tires. I've run PSS's for several years on the Boss, but I'm trying the Indy 500's for the first time. In short, I was worried about the narrower tires (I was running 285/35/18 PSS but could only find the Indy 500 in 275/35/18) and tread squirm, but I was happy with them up to that point just driving on the street. I had the chance to drive on them for three track days now. So what were they like? After my first session, they made an impression that basically persisted for the rest of track sessions on them. Phenomenal, unmatched value. Now, if value is something that stands out above all else, it typically means the compromise between qualities you want and those you don't is less than ideal, but the value is attractive. This is no different. I'll start with the bad, which really boil down to two: ultimate grip and grip longevity. Grip is noticeably l
