Okay, finally went through with the mod tonight. Haven't done a lot of driving yet, but from what I feel so far I'm disappointed.
- Certainly no gain in low-end torque; all I feel is a loss in power, still staying at my usual <3000RPM.
- Valvetrain seems to be much noisier than before, despite adjusting the valves as part of the process.
- Not enough data for fuel economy, but my two short trips both showed a decrease from the norm, based on the ScanGauge. I'll try to get at least half a tank for comparison's sake - if I can stand it that long.
There seems to be some pinging noises now when under load, like going up steep hills. Is this just a timing issue perhaps, or is this mod just a dud in my case?
