• File 11 (green) has the following mods: Karbonius CSL airbox w/ snorkel, Factory euro headers & cats, PCS Tuning canned tune: 332.41 WHP, 254.27 ft-lb
• File 15 (brown) has the following mods: Karbonius CSL airbox w/ snorkel, eletric fan conversion, full oversized Supersprint exhaust system (stepped headers, HJS race cats, resonated twin pipe and Stradale street muffler): 348.44 WHP, 262.14 ft-lb; video found here

🤣🤣🤣🤣🤣🤣🤣! Yep....Hell A w/ the diluted 91 octane pump gas...sadness! I think if I had 93 or 96 those numbers would be even higher

Thanks everyone! Paul did a great job dialing her in; with just his base tune (canned tune with CSL intake, euro cats and headers), she was putting down 344 STD WHP. After a few revisions, power bumped up to 357 WHP and 268 ft-lb 👍

Now that’s YUGEEEEEE! Congrats.

The gains from step 2 and 3, do you think most of them occurred as a result of the tune ? Or would switching from euro cats to hi flow cats and SS headers be more of a game changer?

You need to tune on E85 for another 15ish whp. 👍

you think the # would be much greater without any cats?
thinking of euro headers, NA section back

Awesome, I have the Supersprint Race exhaust, Eventuri intake, Elbow and DUDMD tune, I don't know what my stock numbers were, but my Butt Dyno was amazed, completely transformed my Cars performance. Those are some impressive gains you got there, Plus I love the color of your Car, my favorite.
