It was $300 for the license, $350 for the tune. They are a big name for tuning subarus around here so i trusted them. Unfortunately timing wise i had to drop off and pick up as they were closing so i didn't get to ask as many questions as i'd like...but like i said, i trusted their rep. Its really hard to say how I feel about the tune though. Driving for a few days now i can tell you for a fact its not anything close to +50 whp. I will probably throw on HFC, maybe headers(maybe not since SC is planned) and get a tune at one of the other local shops. My uprev license is written to my ecu now, is that correct?
Its a 6MT btw. Thanks for all the feedback though. |
Yes the license is written to the ECU so you can get it retuned by any Uprev shop and just pay the hourly rate for tuning.

Had a friend go to them with his G37. They did a decent job. A few months later some of us took a trip down to Austin to UpRev and UpRev still pulled another 13whp out of their tune. Its worth it to take the trip to Austin for the tune.

This is why I am skeptical of all values not derived from a dynojet, ideally with SAE correction (or STD for FI'd cars).
You can't control the weather (and no correction factor is perfect), you can't control every transient trim on the ECU, and you can't perfectly control tire slip, but you CAN control the known weight of a drum and then calculate power and torque based on how quickly you can turn it. Unless a shop gets creative with where they take their ambient temp measurements (and some do...), values across dynojet units are VERY comparable. Too many other adjustable variables come into play with other (e.g., load holding) dynamometers , so very, very difficult to make comparisons, sometimes even on the same car. In any case, the final numbers sound similar to dynojet derived values with similar mods, so congrats :tup: |
Awdtuning are not good with uprev I know from experience.

Maybe khan tuning or jotech |
I even tried Jotech. It kept throwing codes. Mainly that the car is running too lean. If I were to do it again it would be at uprev in Austin.

There are some brand new EcuTek calibrations that were just released. Anyone telling you they'll give you gains of 50+ hp on an NA car with nothing but a tune is full of .. you know what. But are there substantial gains to be made from the tune? Absolutely. EcuTek is really going to give Uprev a run for its money, especially when the RaceRom features get perfected. You guys should check it out!

50 hp off a tune alone? highly unlikely. that first number sounds waayyy low. the after is just about right tho :)

More dyno curves from AWDTuning
Following up on your low stock numbers, Keith gave me this printout comparing stock (RED), another CAI+CBE mod (GREEN) and mine (BLUE - JWT pop charger + FI CBE). As far as your stock numbers, they don't seem to be that much out of line with this one. I think he named his Mustang Dyno "Heartbreaker". My tuned numbers are in line with what others have reported getting from Seb & Greg at Speciality Z, so Keith is doing something right!

You didn't gain nearly 20% in power from a tune on a N/A car... it's impossible. Maybe if 2 cylinders weren't firing and now suddenly are...
Mustangs and all other load holding dynos are superior for tuning, but not for taking reliable, repeatable, and meaningful measures. Whatever you made stock will remain a mystery (but was probably around 275 - 280 on a dynojet). Find a dynojet, and you will have numbers that can be more easily compared to other vehicles measured on other dynojets. They are very, very consistent from shop to shop model to model. Only weather and correction factor choice will obfuscate things -- no correction factor is perfect and treat SAE as a "lower bound" and STD as an "upper bound" on what you will be actually putting down on any given day under those approximate ambient conditions. Anyway, something in the 295 - 300 ball park is probably close to what you will find on a dynojet with those mods. Perhaps a bit more with nice weather and generous correction factor. EDIT: Whoops, I didn't realize I had commented on this already some time ago... :p |
