Yes, I can agree with you, which is why I can't understand why people think that HKS is over rated and overpriced. If you have reduced your sparkplug gap previously, you may now want to open it up a little more.Jim Swantko said:I recently installed a twin power on my car and I honestly cannot believe the difference it has made. The throttle response is MUCH crisper... and those little stumbles I use to get on occasion with 4th gear pulls are gone. This little thing REALLY smooths out the pull at higher RPMs. If you are experiencing missing at higher boost (18-19 psi on pump gas) and higher RPMs ... you should seriously consider the Twin Power.
I am VERY happy with this purchase... thanks to Billy Cha for being so easy to deal with for his used Twin Power.
