Looks good for what it is, but you need to get to full throttle before 5700 rpm
Boost tapers down significantly around 6K rpm so your log does not reflect the high boost segment at lower rpm.

Try starting your run from 2500 rpm in 3rd gear and get to full throttle sooner.

I don't like how it looks, I would get another one. Too many throttle closures. Was your traction off? Give us a nice 3rd gear pull starting from 2500rpm. It will also help if u tell us what map and gas you are using

Bro I would log the default COBB parameters. You need to log timing for every cylinder and that is one way of knowing if the map is too aggressive for your car. Please redo.


Ur first log had the default parameters. I don't know why u changed it

I'm a noob when it comes to logs. When I look at the last one it looks like only cyl 1 has any timing corrections. Is that normal or am I reading the log incorrectly?

That looks very good for an OTS map.

That is correct. In this log, only cyl. 1 is showing any type of corrections - and it should be noted that the correction is small and brief. The advance curve looks pretty good for 91 octane.

The car pulls very strong. Cyl. 1 might be the new injector that I swap out and did not code it.

I would code it ASAP. But that's v unlikely to be the cause of that; the timing pull is modest and recovers quickly. There's no reason to worry about that at all, the other five cylinders are quiet as a mouse.
