So If you have taken out that restrictive Cat but you still have the SAI in working condition, you will probably be looking at one of the new tunes without SAI, ( just to make sure you are not running too lean without the Cat), if so. Read on
I tried several of these tunes and they tend to have quite a burble on the overrun and deceleration. Many others have made this same observation. ,
20546 even turned my bike into a fire-breather (which was nice, but not quite desired), performance of 20546 was pretty good, with manageable snatch
Now in TUNE ECU all of these tunes have the SAI box unchecked by default.
TICK THE SAI BOX, download and be amazed by the performance and smoothness of these tunes it's quite amazing.
I hope this isn't something everybody already knows
but I did some searches and found very little.
I also hope that this is not something that only works on by bike, I can't imagine this is the case as the change is so profound.
Try it and let me know how it went, I would be very interested to know the results
