[QUOTE="bunk22, post: 15787361, member: 7921"] ...now this may be a happy dynojet but I've done all my dyno and tuning with this tuner. He actually street tunes and fine tunes on the dyno. His dyno is in bas shape, outside, doesn't sue a fan but who knows who he has it set up. Anyway, on to my car. It is a 2015 Mustang 6 speed auto with a Circle D 4c 3800 stall converter. As far as power mods, it has a JLT, GT350IM, 1 3/4" long-tubes, x-pipe with no cats, axle-back, custom E85 tune. The car came stock with 3.55 gears, it is the Premium Package. Here is the last dyno, hard to see as it is on a computer screen outside. It peaked at 453.6rwhp/400.0rwtq SAE. [ATTACH=full]1455999[/ATTACH] Here was a before and after tune using the E85: [ATTACH=full]1456000[/ATTACH] Now I get this is just dyno tuning, a dyno can be high, low, etc. The shop does run their cars at the nearest track, about 100 miles away. They typically tune high end cars, meaning 1000hp plus so mine is a bit on the weak side. I have not run mine yet to back the numbers but I have used his shop and dyno for all my tuning. I will say the absolute best mod was the Circle D converter. Felt like my car dropped 200lbs and in track mode, just drives like a beast. Anyway, thought I'd share. [/QUOTE]
