I dont have the before Dyno sheet. The fella that did the test told me that you loose 15% through the drive train so 289 /.85 = 340 @ crank which is 35 over stock. Did he tell me a load of DUNG? What to these cars dyno at the wheels stock about 259hp which would be 305 @ crank? Have I been living a lie this whole time? Any way about my original question (how much HP can be expected from a good tune)?
I dynoed 268/291 but the weather wasn't pretty. People up north dyno in the 270s, so if with full exhaust you dyno 289, you might need a serious tune. Theres 1 guys in south florida that had intake/midpipe and dynoed 276 and after the custom tune he put down 298 and torque somewhere around 310.

I have the same mods as tubbamach, and i pulled 265hp/278tq on a mustang dyno. Not sure if theres a way to translate that to dynojet numbers, but i was told u multiply by 1.1 which = 292hp/305. So im roughly the same. Again tho im not sure how right that equation is.

Not to highjack the thread, but thx for the clarification on the 1.1 multiplier from the mustang dyno to the dynojet. Stuff gets confusing and I wanted to know that for when I go get mine dynoed. It seems like every single dyno sheet I've seen on stock Machs are from 275-279rwhp. What mods do you and tubbamach have to get you guys up to the 292/305 ? Thx man.

That's sounds low for an intake and a full SLP exhaust. That's only 15 hp increase over stock, give or take maybe a couple. Would think it would be about 10-15 hp higher. Trust me I ain't busting on your Mach, I'm just thinking you're prolly making more than that.
