yo thanks for getting the car cleaned despite being a very sudden notice (like, an hour prior LOL!)
not to mention the increased timing so my car would be much more quiet/stable during idle times and that means less interruption to my ICE

as for the product feedback:

- definitive improvement, mainly on the accelerator "lag" being almost gone. what i step on the pedal is what i feel. flooring the pedal also felt much stronger and more responsive than before, floored, have to wait maybe a sec or so for the engine to kick in, wtfmuch lol.

- engine is roaring now, not in a noisy kind but a rather deeper "refined" sound than the previous "totally lack of energy" sound.

- seeing the RPM meter actually going up high with every hard rev is quite surprising for me considering how the car felt powerless before using this

- i can actually accelerate >120-140 pretty damn easy compared to the previous "floor the damn pedal for at least 5+ seconds and patiently wait for the speed to SLOWLY climb"
