because i can switch between stock tune and evolve tune i could do dyno both ways. i do have other mods though so wouldnt give the full story. primarily the cat delete. would be a pain to take out the exhaust and reinstall between runs. my exhaust leak is partially fixed so much less noise confusing me thinking its faster cause of that. it is for sure quicker in the upper ranges especially but even down lower at 4000 i bet im making 25 more hp and about 40hp at 8000. its usable and noticable.
