I'm driving saga blm for more than 1 year, so far the following happens on my car:
1. Driver side power window switch 50% working, so got new 1 replaced, while passenger seat one starting to follow the symptom
2. IAFM part (Forgot what name edi) keep producing tick tick sound when engine running. Got it replaced and no problem until now.
3. Wheel keep sway to left side, went to proton HQ, alignment and camber checked without any problem but suspect is steering rail problem, waiting for the part to come and replace in near future.
Before the car being tuned, i always feel it underpower, check what i have done on my car:
1. Have strong magnets clip on fuel inlet line. (Avoid buying those fuel saver brand because they suck up your money while you can get much better magnets at jalan pasar with 1 to 2 time lower cost.
2. Have strong magnet inside air intake. Please don't ask me how this work to improve power but it really improve engine power where you can feel it.
3. 50K Farads of small to large capacitor mod on my battery terminals. With this mod, my car engine can drag to high rpm smoothly.
4. Denso iridium plug IT20 installed.
With item num 3 + 4 installed, you can easily drag ur car rpm up to 5k when accelerate, the engine doesn't sound harsh like you're giving pressure to it but it does it smoothly.
