We skipped Laguna and Lime Rock due to other commitments and distance from the shop in Charlotte, plus we needed some time to get a handle on some of the teething issues we were having... to re-cap issues:
Fixed the mixture issue and picked up about 30-35 RWHP with a tune from our friends at Palm Beach Dyno, they worked with us on some baseline and data gathering to come up with the proper parameters. She made 520 rwhp on the Sonoco 98 spec fuel.
After some fiddling, we finally pulled the ABS fuse to completely get rid of any intervention.
Results are we're getting closer! Power was sufficient to effectively match straightaway speeds with the Billy Griffin's GT4 Mustang, GT4 M4, Audi R8, and the 2 Porsches. We managed to get to the High 1:32's on way old tires. Full lap times don't reflect the potential because we had another issue crop up, low voltage.. We believe the zero gravity ultra light battery (7 lbs) isn't compatible with the charging system and the voltage drops through the race, causing misfire codes. If anyone as experienced the same, would love to hear your advice.
We were able to make some strides in handling balance and shock settings, but there's a so much to try on that front. But, we're charged up that the car has proven last weekend that it WILL be competitive.
Onward with development!

- Mixture going rich to 10.6:1
- Traction control interfering, even with the dyno plug out and the advancetrac turned off
