I've been running a (Vortech) visconti and FA20club tune for a while... and I've been switching back and forth to compare them.
I'm going to be honest, overall I like the Visconti tune better. The power below 4500rpm is VERY noticeably stronger/smoother. FA20club high RPM pulls better... but for around town it is painfully apparent that the other tune feels sluggish.
Say what you want about Visconti (and there is plenty to say at that
) but when it comes to my personal experience with his tune... I like it enough to use it over the FA20Club tune (a tune I purchased specifically so I did not have to deal with Visconti)
This may change once some more logs are sent back and forth... but on the logs it seems like both maps have fuel dialed in very well, the main difference being cam timing down low.
Visconti tune is 1.06 basemap
FA20Club tune is a revised basemap after 3rd gear pull and 1-6 shifting like normal
