I think we should all wait for the RR Racing tune. I spoke to Rafi last week and he gave me a bit of insight of just not the tune but of the IS F in general. He's very passionate about the car and definitely wants it to be competitive in its respected segment. I have full confidence that he's working the ins and outs of this tune, so it runs smooth and perfect. I think his team has proven themselves to be very serious about taking our platform to the next level. We owe it to them to be patient...and the best part is that they own an actual F. Not like these other shops coming out of the woodwork and all of a sudden figuring our cars out.

TTFS actually has a very good reputation and following on the ///M forums. He has tuned a lot of cars and makes great power. He may not know this chassis all that well, but I wouldn't write him off as a potential future asset if they too have the ability.

I'm guessing he's going by his "low" reading dyno.
With headers and exhaust, on an average DynoJet would yield approximately 400-405whp. If you calculate for approximately 17 percent drivetrain loss that would net around 490HP at the crank.
If you put that car on a average reading DynoJet with his tune, he would probably be making 430WHP+ which does translate to "about" 520HP @ 17 percent drivetrain loss.
Then again this is all in theory.
*Edit* damn, I just realized if those power gains are accurate we're approaching LFA power levels out of our NA V8's. Imagine if we could rev out to 9000 also? Boom, 650HP baby.

I know we've all been promised before and never delivered so we're accustomed to looking at "tunes" with skepticism. It looks like the real deal this time and the ISF is making great power (according to TTFS and Vivid Racing) so let's all rejoice, it's a great time to be an ISF owner.

Can't wait to see what the aftermarket has in store for us in the next year or so.

Spot on. Plenty of reputable tuners will be able to make gains with a remap but I would rather use someone who pretty much eats, breathes and sleeps ISF.
The map on my Galant VR4 is one that had months of development before being released and tweaked along the years. It was used reliably on plenty of cars before I had it flashed to mine and it's been faultless. I'm looking for the same for my ISF so I'll happily wait for Rafi his team.

I really doubt there will be anything gained above 7k rpm before someone ports the heads with bigger valves and comes up with cams capable of taking advantage of the port work. Seriously.
