Any idea, what is the best turbo timer? Ist HKS Type-1?

All I can say is two people have installed the HKS type-0 without any problems. One person tried an Apexi and is having problems, another tried an HKS type-1 and has problems. No idea why either isn't going well.

I got the GReddy, but have yet to install it. Hopefully I won't run into any problems.

as long as it works, doesnt matter what brand.
have had apexi (pen style) and pivot super baby timers, and have had NO problems.... have also tried mechanice style (ie. ME), that worked fine also.... :D
the rule of thumb is that for the last couple minutes towards your destination, take it easy :)

I had all of them and only one I hated and had problems with is the apexi t.t and blowoff valve for that matter.greddy was easy and never malfunctioned,hks but pricey
