my review would be the engine sound a bit more harsher.myb because i used it with petron ron95?
cold start require the rpm to shoot quite high at around 2k rpm.just for a mere 1 sec.then drop to around 1.5k rpm for warming up.
however the best part is dat, it really help to save more fuel.1 full tank can give another 20 to 30km extra.
the performance is indeed there.coz when i stop using the 2t...the car felt require more power when going uphill and i find it giving less mileage.
calculated fc is around 14 km/l.before use 2t its around 13km/l.this is for daily go to work use.
btw, i tried on my perodua viva 1.0 auto wif complete exhaust, open pod n e manage.
