Maybe im just a bit paranoid, but this morning i was going onto the highway from the on ramp, and i am not being aggressive in my driving or accelleration. I knoticed that my car "felt" like it has having some instantaneous "hard pulling". It felt like for maybe 1 second increments, the car was pulling hard, then lets off (almost like hitting bumps on the road, but peing pushed forward by them very briefly). My pedal was around 25%. It did this too me maybe the higher gears (4th and 5th). It didnt do this constantly either, only intermittently. It also seemed to occur more often when going uphill. Engine RPMs are not fluttering at all either.
Car is Stage 1 OTS tune with only CBE and drop-in panel filter. Maybe im not used to how the stage 1 operates typically because im so used to the economy tune on my commute. Didnt knotice this issue last night when driving throw the mountain roads either, and babied the throttle still.
Again, maybe im just paranoid and will plug in the cobb and observe boost levels as im driving this afternoon. One thought is the altitude sensor adjustments. On a weekend basis i drive from around 5,500 ft to 9,000+ ft one day, and the reverse coming back for the weekdays. So, maybe the sensors are readjusting to learn the parameters of the air at 5,500 ft.
