I have just updated to a 80mm tb and yes it does appear to have made a difference to my 290, But iused the tb with the helix allready machined into it rather outlaying for another helix. I have heard differing opinions on the 260.
What cold air did you use? I changed from the ss (herrod is the same) to a bluepower cold air and the difference was very noticeable.
There is no substitute for cubic inches but my pursuit sure closes the gap
*UPDATE * Pursuit has just run 11.763 and 116.18 mph making it Australias Quickest and fastest unopened boss as well as Australias Quickest and fastest naturally aspirated Boss
