My 2nd input on LCP on a stock car (no other mod, no drop in filter, no iridium spark)...

My earlier comment on the harsher engine noise....its somewhat reduced now, still slightly higher than usual but not that obvious anymore. Probably becoz I've readjusted my foot's pedal acceleration to fit the LCP new increase torque curve. I think I might also get used to the slightly higher sound liao coz it's not so obvious anumore.

Have learned to tekan less when accelerating to comform with new acceleration torque and it works well. It changes gear especially from 1st to 2nd and 3rd, very fast. Can still feel gear change jerk slightly but due to my right feet changes, its much less obvious.

No more hold back feeling of car when accelerating after passing smart tag toll gates. Just zoom much faster than usual. Trying to control feet to slow down a bit to save FC rather than overaccelerate like what I did yesterday causing more noise, harder gear change jerk, etc.

I could close gap much faster during traffic start/stop jam in the morning. On a single lane road, previously when I try to overtake a vehicle from slow speed, it takes a couple of seconds for my H-line auto to pickup speed, by then I have to swerve back in liao coz opposite car coming. Now it just accelerate and switch to gear 2 fast and I'm off to the front of a slow bus. This happens at slow speed drive where H-Line auto acceleration is weakness is very obvious before LCP.

Overall, my doubts on the pro vs cons (better torque curve vs noise/gear jerk) leaned way ahead towards the pro as noise and jerk is greatly reduced with new acceleration control by my right foot. Of course, being a cautious guy, I still have doubt a bit on vibration after effect on long term. But what the heck....

Now seriously looking at stiff ring to try to solve my possible undercarriage issue (when up or down parking ramp, the steering rack somewhat crank crank crank). Tot is might be steering shaft but last time, supposedly tighten undercarriage by Cose, it dissappear for a very short while. So suspect it might just be undercarriage problem as well...
