60 ft was good. 1/4 mile was good. But has dragy running also. And it recorded me 100-200khm at 7.2 seconds??? What's up with that?? Seems extremely slow to me.
Good run. The 100-200 seems a little slow to me as well with your et and trap, but not too far off. I looked back at my 10.8/9 @128.5 passes, and I was at 7.01-7.04s 100-200kph times.

It's also interesting that Dragy gave you conflicting info from the time slip; of course they won't be exactly equal, but there's a larger margin of error present than what I typically see.

The big question here is...what's up with the 7 second 100-200. Like I said IAT was bad. And I'm sure my engine bay was hot because I was speeding heavily before I got there... But even with all that.. 7 seconds!?!?I'm seeing f90's in the low 5's.

I'm adding meth injection as soon as burger tuning releases it which I hear is very soon...I'm hoping that will solve the problem

I did. I don't know which one it is though. I had 6/7 logs all around the same time so no help there. however I did send all of my logs to Payam atBurger and he said the logs look just fine. also said the times are restricted by the IAT.. Not sure though. Like I said. 7 seconds is wayyy up there.

i'll have to take it back on a colder day making some comparison.

I don't know how to save them from my email and post them here. I can email it if you want to take a look.
