Visited drag strip yesterday, no results(13.1/195). Missed 2nd to 3rd shift three times in a row. Tried different launch technique than before and rear tires were starting to lose grip at around 4000 rpm in 2nd gear. I need more practise, there is still at least 3 more race events to come.

Winter update:

I ordered new rear wheels and tires to help get some more traction, when visiting drag strip next time.

Wheels are 17x10 Forgestar F14 and tires will be 28x11,5 Mickey Thompson Et Street R bias-ply. First I thought Et Street radial would be good choice, but avaibility and out of roundness is an issue, I have heard.

Added 3-way switch to NPP-exhaust system. Used the guidance found from this forum. I put the switch to lower corner in the center console box, next to power outlets. Huge difference in the sound with the muffler flaps closed.

Replaced cracked windshield with my brother. The drivers side was like that when I got the Camaro, passenger side cracked during removal.

This knock table from log is why I had to return to US-made tune in last summer. Some tuners should not advertise themselves. He blame the DSX pump system, but problem was the MAF-curve he guestimated. Well I left the closed loop settings on.

Dynoed my Camaro in early November with my fuel pressure settings. I used same settings whole last autumn.

Those numbers are at engine, not rear wheel. It made still lots of power.
Lots to improve in fueling settings. At 5000rpm dyno rooms lamda sensor fell of from the pipe. My log shows that AFR tapers down to 10.2. This pull was with 530kpa (~76psi) fuel pressure. Those number are close with 1/4 mile calculator and my so far best trap speed (209kmh/130mph).

Had whole winter time try to study how to tune myself. I will see how it turns out. First start up with new "improved" settings accomplished yesterday.

Thanks! My first task is to get fueling to 11,5 AFR / 0,78 and make little driveability improvements at the same time.
