I put down 352 on church's dyno without a tune. Get on my level noobs. Haha jk. Good luck!

 

I am interested to see what my car will put down again now that i swapped out the injen intake or a Stillen gen3 and now have more than 3k miles.

 

Are people still having these issues with the Uprev tunes?

 

Uprev was never the issue. The issue was that people were either dynoing incorrectly, or with an uncalibrated machine. An uprev tune will increase your horsepower by virtue of it allowing your ECU to take advantage of whatever mods you put in.

People are getting all hung up on one number or another, but you can take two dynos and put the same car on each and get different numbers. It's a diagnostic tool, not a measuring stick.

 

Well put.... The base line pull and the final pull aren't the end all be all. The truth is in the Delta between the curves. Thats why I have been screaming about all these so called "tuners" that are the best..... Yet have no dyno? A-holes.

The shop I'll be getting my Uprev at has a calibrated Mustang ?550? dyno. It's new and the tuner has done over 500 Z's and G's so I am comfortable with the shop. I'm told my base line will most likely be in a range of 240-260 BWHP then the Uprev should get it to 300+ BWHP. I can live with that.... I can really live with that. He wasn't trying to sell me, I told him my limited mods and he shot me numbers from his experience. We will see.

 

Not trying to starting anything but that sounds way to high if you really are 240 and reach over 300. Most Z's are in the 270's and just break 300 with tune, intake and exhaust. You can baseline and final dyno all you want but with one click of the mouse a mustang is insanely easy to mess with. It takes a dozen things to set up a run within the computer and if any are off or messed with you get different numbers. I hate mustangs. If the tune doesn't go well with a happy customer, or you want to look like a good tuner, change the tire diameter and boom, more power that you can't see on the sheet. A dynojet is untouchable kinda. You get 3 settings, STD (targets to low of a air temp correction factor resulting in about 4% to high HP), SAE (what the industry uses for all cars and is best proven by trap speeds at the drag strip because a car can only cross the finish line in XXX MPH if the car weighs XXXX and has XXX power within 1/4 miles), and uncorrected (which always reads low which I believe is the actually temp in the dyno room). The beauty of a DJ is you just spin a 3000lbs dumb and your power is what it is! Since all have the same software to calculate power, it's the best to also see what you run on SAE vs your buddy in another part of the world and truly know if you met up who's got the bigger *****.

 

He's correct, however your gains from just a tune without adding boost.
YOU WILL NEVER MAKE 40BWHP from ANY TUNE n/a tune on vvel vhr.
the proper term is whp (wheel horsepower) crank/flywheel.
Please tell us where your getting your #s.
Btw I was tuned 1st with Cobb then Uprev about 4 years ago.

 

I wish Uprev or anyone would crack the VVEL ECU. That's when the true N/A street power of this powerplant will be availible to mere mortals. If they could the results would be similar to the tuning response of the VK56. With Uprev it produced a felt response to every single mod. From my first intake all the way through to JWT cams and a 90mm LS7 throttle body. The independant VVEL ECU and that "Magic Screw" ( Like a free set of cams minus the labor ) are the keys to the Bolt on "12 seconds" kingdom.
