DA was around 280. IAT was 82 at the start of the run and 64 by the end. Boost stayed between 19.5-21.1, tapering in the higher rpms. Timing peaked around 17 and there were a lot of corrections. I typically get less than 2 degrees of corrections on 75-80 degree days running 93 and ing. 1 going as high as 19.5. Which is why I suspect the fuel not actually being 100 octane.what’s your DA? Lozic tune seems to act conservatively when it comes to high DA environment. Me and Pearly are using JB4 to add more boost for 4500,5000,5500,6000rpm by 0.5 to 2 psi to milk more high end power and it works great. Go check your boost curve for a full 1/4 run on JB4 and it might gives you the answer why you’re slower than you expected.
