Congrats! What are you running for tires? Is your trip computer working correctly? Mine is reading way wrong after the Osiris tune.

PLEASE PLEASE don't chase 500WHP it's a FAIL.. Be happy with what you have. The kit is GREAT for the numbers you made don't change a THING Cough cough Heat exchanger that's all you change!!

I know the FAIL first hand

My Frozen Boost intercooler is already on the way thanks to ANMVQ's recommendation. I also agree that 500WHP is is a low probability event with this SC. If you wanted to crack 500 you should have gone with a turbo. Besides, with a 2 wheel drive car all you will do is create more traction issues.

Can you post your dyno chart.... I'm interested to see what differences there are between a generic Stillen tune and a custom tune that I got. I know the number comparisons are irrelevant with different dynos, but I am interested in the shape of the power curves.

Really compare a Can tune from Stillen( 342 WHP) Custom tune 412 WHP. We know dynos are different but 80 WHP

you know I couldnt let that go by LOL

He has tunes a custom tune not a can tune ..

I hear you... and its not just the peak numbers either but the area under the curve, that's why I was interested to see the graph. Someday when I get my stuff resolved with Stillen I will tell about the absolute gong show that I had to endure... thus my reference to "the journey"

ANMVQ.....342 WHP????? So low =0. Also....ya I'll post the dyno when get back to my car (I'm working at the moment....off at 445)....dyno chart is in the car. But....342 WHP? Why so low? There's a dude on youtube named Blossomgame that made made 347 WHP with no forced induction.

I have a hard time believing NA car putting down 347. That must be quite the dyno LOL. Wish for a number and out it comes

I posted a graph with my NA car with intake and exhaust mods and a custom tune and I made 284HP. On the exact same dyno with the V3 SC I made 443HP. So it is not so much that the final number is important, but the difference after forced induction... and for me that was +159HP. Maybe on the dyno that gave a generous 347 for NA I would have pulled over 500 LOL.

I made a mistake. It was 334. But still....that's quite low when you compare it to what's possible on a stock motor with no FI......342 is almost like you're not even boosting the motor.

The scale on your chart for TQ is different than mine so it is a bit misleading to compare the two as far as linearity, but the numbers are almost exactly the same. at 3K I'm at 250 ft pounds (same as you) and at just under 5K you hit 300 ft pounds and so do I. Very similar results. Thanks for taking the time to post the chart.

What octane are you running? I am using 94.

One other question... did you get the rev limiter adjusted? I have mine set at 8K as the car is still making a lot of power at 7500. Before I had the SC I would never push it as it was just not making much power above 7K. Very different story now

You would get some more ponies with 94. That might account for my slightly higher numbers. I had the them optimize the tune for 94 and also put in a 91 tune so if I get stuck with normal premium I am still OK. Osiris lets you shift tunes on the fly so it is really convenient. Also have a valet tune with limits RPM to a max of 3K. Nice to have that security when you leave your car for service or parking.
Changing the rev limiter is super easy when they are doing the tune... its just one of the parameters they can set. I am surprised that they didn't ask you what you wanted it set at.
