+ 55 whp Tune. Mustang Dyno

antisocial83 · 05-24-2013, 10:24 AM

Just got my uprev tune at awdtuning (texas) I was expecting 15whp +/- but the mustang dyno shows 237 before and 292 after (234 TQ). I only have topspeed catback with resonator,y-pipe and short ram intakes. Ill post the dyno sheets today if anyone is interested. I hear mustang dynos read quite a bit lower?
I havent got too crazy on it but it is noticeably smoother. Hopefully this will hold me over for a little till I go FI.

makes me wonder what your tq was before if you were so low on the wheels. Sounds like maybe some numbers were fudged.....

Yea thats kind of what i was thinking but wasn't sure. The tuned hp seems in line with others but I thought most people started ~250 .
I get home in a few, ill post all my numbers and graphs.

The other print outs are at home.

Ya that is too much of a gain with just bolt ons. Hopefully the tune numbers are correct and it was just your starting off numbers that were wrong b/c 55+ you would feel like your driving a whole different car. In the end the question is are you happy with it?

What gear did he use for the pulls? What RPM did he stop the pull? Those are some thick A$$ lines on a graph LOL looks like a kid did it with a magic marker

Mandingo · 05-24-2013, 11:32 AM

Do you have the sheets showing the A/F ratio?

antisocial83 · 05-24-2013, 11:37 AM

Yea, and though it is noticeably smoother/more powerful, It doesn't feel like a whole new car. I figured it was low, but its always hard to guess with inconsistency between all dyno readings I've seen. Time will tell if I'm happy with it I guess. But hell, I have the license now so worst case I throw on some HFC's as an excuse to get another tune.

SS_Firehawk · 05-24-2013, 11:56 AM

Maybe he wasn't full throttle on the first pull? Both pulls cut short, so I'm thinking they were done in 5th and the Speed limiter wasn't removed.

BlackZ85 · 05-24-2013, 12:45 PM

Maybe he's running really rich like me, I got 279.8 and 216tq on a dynamics with exhaust and intake

NickTurnon · 05-24-2013, 12:52 PM

When I dyno'd my car, they couldnt dyno in 5th (7AT) because i hit the topspeed of 155mph in 5th gear.. So they did mine in 4th gear. Same numbers apparently..?

Anyways, those are good gains, however I think on a 6Spd baseline is around 260-270

Motion Lab · 05-24-2013, 01:42 PM

I wonder if it was spinning on the dyno for the first pull? Either way who cares as long as you are enjoying the final results!

Thanks,

Damn, but I'm sure they didn't get the right reading? How was the experience there? I thought about getting tuned there.

Why didn't you raise your redline? How much did they charge?

I wish I would have known, maybe we could have gotten a group tune deal.

ChrisSlicks · 05-24-2013, 02:31 PM

I hate to say it but it looks like they may have played with the correction factor given the way that the two torque curves are presented. He could have been running pig rich but even still ...

Normally the correction factor is controlled by the atmospheric sensor and is typically somewhere in the range of 0.95 (scale output down 5%) to 1.05 (scale output up 5%), however the operator can override this and some tuners play with the value to make them look like rock stars.

I think a stock car is around 255-260 whp on a Mustang dyno and with that level of simple bolt on mods I would expect around 270-275 after tune.

Bottom line, if the OP really picked up 55hp then that should be very noticeable in the old butt dyno, so it is up to him to decide how much was smoke and how much was real.
