I'm not saying they don't get results, I'm just querying the relevance of the numbers in the names of the packs in question.
I don’t know if relevance is totally the right word, indicator is probably a better fit as there is no real accuracy in the numbers of an advertised pack but I definitely agree with what you’re saying.
I don’t know any of the serious old school tuners around Sydney that make output guarantees, at best they’ll give you a rough idea as to what sort of increase you could normally expect.
Different engines making different power from stock will play a part in the final outcome.
I’ve never bought a pack off a tuner.
When I walk into a performance shop it’s to talk about what I want to achieve, the type of cam I’d like, where I want the power to come on, how it’s delivered, the type of revs I’d like to make and so on and the same applies with any other items such as an exhaust or a turbo that may be fitted.
The tuner gives me advice on what’s needed or maybe some sensible alternatives to pull my head out of the clouds and I get a before and after dyno report to give me an indication of what type of increase was achieved.
We all know you should never trust chassis dyno figures as they are just a tuning tool and packs well they are just a known combo that works and some engines will react to them better than others.
Dyno sheets for bragging about your power output are as valuable as used toilet paper.
