Well I got a 60 hp difference after a tune so I am happy.

I know f**k all about dyno's so thats why I started the thread after I read that paragraph on the mainline dyno website.


What I thought this thread would achieve was someone who knows the difference between the DD dyno and the ML dyno and could explain the difference in inputs with all things being otherwise equal.

Unfortunately, as I outlined above, even if you got two identical dyno's - there's still uncontrolled variables - you'd still get different answers from them.

60hp on the EL XR8 (you're profile?). Impressive.
