Usually around 600 or more, you buy the cable (software is free) and then the dyno time is usually built into the purchase.

So the $600+ is for the cable and the software is free? And dyno time should be free. Im used to tunes that you just pay $500 and they copy a new file according to your mods to your ECU. Granted they are only 95% of the performance but well worth the price.

If its jsut $600 then I would probably pay that much for 30 more HP/TQ.

I didn't have to buy anything, I just walked in, paid 788, and walked out with 30 more horses haha

Thats how I would want to do it. But maybe less than $788, more like $600 max.

G37 what was the lowest gain and the avg gain? Im looking more for a consistant number thru all the rpms than a high number.

Well it varies from shop to shop, you should check up uprev.com and find your local tuner and get a quote from them. From what I was told is you can just get a tune & dyno time or you can also buy the cable so you can access it when you want without going to a shop.

Man the closest place is like a days drive for me.

the before and after dyno were done on the same day?

Within an hour and a half actually

Since this isnt a a static tune that is the same for all Zs, its really up to the shop tech to get everything right for numbers like this right? So one shop might get it and another might not unless they share notes.

Not all engines are the same, if I upload my map and send it to you, even if you may have the same mods you might not see the same exact gains. My tuner did around 7-8 remaps before walking over to me saying "Sam, I don't think we can squeeze any more out of her"

Now do the other shops know what he knows and can do the same or better, thats my concern since its not coming from a master database or something like that. I would be fine paying $500 for a tune according to mods even tho it might only be 95% perfect, thats still better than nothing. My other FIs werelike that and they worked great. A couple people spent more money to try and get it to 100% and they only got an extra couple of hp out of the 1K cost. Most CAIs and aftermarket exhaust make about the same gains so it could be feasable but Im not 100% sure due to the vvel.

What does the VVEL have to do with anything?

People are pushing 10 pounds of boost without even touching the VVEL..

I didnt know if it did or didnt. If we were close I would have the shop copy your map and put it in mine and see how things work, assuming we had the same mods and of course same car. Im pretty sure it would be very close in numbers. Thats why alot of turbo tuners just create several maps according to mods and you just pick and upgrade as you go for free, after buying the initial tune. It was actually more profitable for the shopas they didnt have to do dyno time and still got $500 for a file they downloaded from the main companies database. It took about 2 hours to drive to the shop and 15 mins for the file change and all was good.

I hope uprev is keeping a copy of these maps on file for future references, then they might jsut be able to sell the file without a dyno tune.

That is a solid gain from a tune, your motor will be much happier now, why would your tuner not share the data? I am guessing probably 2 degs added from looking at your TRQ, the AFR would have netted you power.
Love the comment on the rear end breaking at will, now that is fun

It's not necessarily about the numbers themselves, but about the gains seen from stock to tuned. That's the important stuff!

You cannot duplicate the exact same variables from one moment to the next, even on the same dyno.
