Ah, at last an awesome productive thread with no bagging-out!
In the past, I've only ever used SST for my car. Albeit only insignificant things to some people, ie tuning AFC etc. I've always found floods of advice forthcoming, and always good for a laugh
I've been to other workshops in the past too, but never ended up doing any business with them due to them being "Not interested in the small jobs" so to speak.
That said, I've never had dealings with Hyperdrive as everyone else highly regards, and if they supported the ECU of my choice I have no doubt they'd be seeing my car also. I've seen both Ken (Hyperdrive) and Steve(ex-SST) post nothing but good advice on this forum over the years and that instills confidence.
So a big thumbs up to you guys, and a big thumbs down to the unnamed "cant be stuffed with small jobs" workshop
