All will be revealed on the 27th folks
I have found promised bhp increases are rarely exclusive to one item. They are normally achieved interdependently through a package of tweaks rather than separately.
That lessens the individual tweaks effect and makes dynos the ultimate humblers, though still the very best tuning devices and LOTS of fun, which you are certainly having.
Do you intend to try each one by one?
I look forward to the tale of your adventure.
