Great results and right in the ballpark of what should be expected. Did anyone log their KCLV values as we know this will have a big impact also.

Speaking of real world data, I think we all know the F performs better in the real world than on the dyno. Here is my latest Virutal Dyno run from yesterday. SAE corrected. This is on a very straight, flat, smooth section of Interstate. I have done 7 or 8 pulls there now and it is very repeatable. My baseline before tune was 388rwp. My high rpm KCLV value was 23.6 during this run. I/H/E/T

Rafi - very nice!! Major area under the curve. Maybe I should move to PA.

First run of the year. The DA was around -1500 and it was very difficult to get traction. I couldn't hook up after that first run which was a shame because I really feel like I could have hit 11's. Now that my KCLV is in a more acceptable range I really feel like this tune is the real deal. My best times last year were in the high 12.3's with -1000 DA's. The extra 400rpms really helps too. i was consistently trapping at 118-120.

Very impressive time. Your 60 ft time is pretty good for street tires. I could not manage to do better then a 2.1 and I'm curious also on your tires you used.

Continental dw extreme contact 275/30/19... I only hooked up on my first run and even then it wasn't perfect. I've had 60' times in the high 1.8's before with just gutted cats and borla. My mods now are ppe headers, borla, and tune. KCLV at 21.4. The track was too cold as soon as the sun went down no one could get traction. My 12.1 was the best run of the night from what myself and my friends saw which is awesome but I'm usually upper middle of the pack there.

Donny and Brian both has more than 300 miles break in period so break in as a much the more u pull the more it stronger and stronger 🤗 so the tuned is there 15 to 20 whp range if weather better could be higher. We have more than 80 degree and 50 humidity.
Should equate to about 500 HP at the crank, pretty impressive if you ask me!
Very nice track number Drok! Be awesome to see 11's in the 1/4 w/o turbo/supercharger!

Nice were these dynojet numbers? So Rafi basically with my mods no cats with the tune I should be in the 425-430whp range and 520+hp to the motor?

Nice to see someone else with a turbo s2k. I got rid of my boosted s2k a while back and got an ISF. Full bolt ons now and still waiting to pull the trigger on the tune. On the other hand, I did scoop up another s2k for a project. My last one was close to your power. You're absolutely right. It was fun as hell.

These virtualdyno plots are getting very Subaru forum-ish.

Do you have the transmission torque converter issue when raising the RPM?

This is a dyno jet approximation based on a software program called Virtual Dyno. When used correctly, it can be a very valuable tool to show real world performance gains. It uses RPM data to determine acceleration and calculate WHP/WTQ. There are many user input variables at play - gearing, tire size, weight, the road itself (must smooth and flat, etc..), drag, etc all play a part. The benefit though is that it analyzes your car in real world conditions with real world airflow, IATs and loading. Static dynos cannot do this.

There is a thread describing how to use it here - https://www.clublexus.com/forums/is-...ower-list.html
