Like the other guy said, ktuner has some basemaps for the W1 with different bolt ons and fuel. But they are only for the Si.
With that being said, they are basemaps, just something to run safely so you can drive it. You should get it tuned.
I would get it. It took me a while to pull the trigger and I’m glad I did. Having DRob etune it also gave me some piece of mind. You can always have normal mode turned way down for reliability and longevity.
Oh and I still average 36-38mpg on the highway on 30-35% ethanol.
Im sure they’re not safe if you beat on it constantly at those numbers. My normal mode that I will be in 90% of the time made 281/288 around 20-22psi.
Also, I think most of it is the early peak toque that the internals don’t like. My torque is fairly low and the curve isn’t crazy compared to...
Didn’t get a chance to do any runs stock. It made 281 on the “conservative” map. I’m sure his dyno reads a little high. He did dyno a stock hellcat and it made 640/620 which is about where they are. In reality it’s probably a little lower to the actual wheels but I’m still happy with it.
