I cant remember but I believe you're wastegated it might just be the flutter of the wastegate. Try adjusting the sensitivity setting on your boost controller if you have one.

3rd motor and already going 140 on the highway with the same tune.... ha ha. Look, do yourself a favor and get a setup to monitor the knock PID while you're driving. This way, if you get some bad gas or something you will see it as an increase in knock retard and you can take it easy until you get better gas. If you monitor knock all the time, you'll get a feel for how happy your tune is over a variety of driving conditions. I wouldn't trust just a single log that someone said is ok. Things change when it's hot, or cold, or when the gas quality varies. Simplest way is an Android phone with the Torque app, and a bluetooth OBD2 adapter. If you go the phone app route, make sure you get an app that can use a custom PID because the knock PID isn't supported on any app that I know of. I think an Ngauge will also do this, but I don't have any experience with that. Torque will allow custom PIDs.
Yeah I know. I'm pushing my luck. Gonna have it dyno tuned and have him adjust my boost controller as he tunes the car. What I've should've done in the first place. The guys at Lund are good but they can't make any adjustments to my boost controller since their not here while the car is getting tuned. 11 12 lbs is all I want. Need to 700hp plus on that dyno sheet
