I have the Hurricane 240 flash with after market BOV .
If I add the SS upgrade , do I need to do anything else ?
Looking for the easiest , least expensive , corner to corner pick me up .
Anyone done this ?
What is your assessment of the improvement .

I would think you'd need the 3bar upgrade. Maybe not if your staying with the 240 SS tune.

I updated to the 240ss and had to add 3 bar map sensor. I would recommend updating won’t regret it.

You might not need a 3 bar with under 15 psig with 240 , but see how much the 270 flash is over the ss upgrade. The 270 flash is probably what you are looking for , it's a lot better all the way through.

What are they doing in the SS tune? Wastegate duty-cycle, ignition timing?

I flashed 2 Thundercats this year with the 240ss tune. Both needed and got 3 bar map sensors.

I don't think you'll notice much of a difference in upgrading the tune, except making your pocket lighter.

Closed wastegate and no leaking BOV? What else can you do to spool faster? New header? Or heat from fuel and changed ignition timing??
Let me know!

me. I have the bundle and flasher. Ss tunes need 3 bar map sensor too, so it’s impossible that’s it’s flashed incorrectly.

I ran both 270sm and 270ss back to back on my sled and could say by my a$$ dyno that ss pick up faster down low!
