the tune is from EVO, however the SCT tuner has those adjustable options
I've posted this before, but will post again.
I also purchased the Evolution Stage II kit, with the tune. My car also didn't feel like it had the same kick in the pants as it did stock, BUT it did feel quicker and faster in a smoother way.
The tune you recieved from Evolution is a "canned" tune...meaning it is probably a little rich, but definitely safe. The tuner I took my Evo stage II kit to, to put on, said there was about 30 more safe rwhp to be had. My tune was on the rich side. At that time I did not want to pay $250 or more to have the car re-tuned, so I left Evo's tune on there. It is safe and the car is quicker and faster.
I dyno'd my car prior to the stage II kit install and my stock rwhp was 412 and rwt was 420. The stock numbers were a little low, when compared to most in the forums I've read. However, my car was dyno'd when it was hot...I had driven for 40 minutes and within 10 minutes of me arriving at the shop, the first dyno was ran. So maybe that is why the numbers are a little low. I can't say, because I don't know how Evo's cars are dyno'd...cold or hot.
The stage II kit was installed within 90 min or less and was immediately dyno'd again. The engine was still hot, but not quite as hot as when I pulled in. My after stage II install numbers were 509 rwhp and 520 rwt. This is a gain of 96 horses and 100 lbs of torque at the rear wheel. The Evo tune was for 93 octane. Note that I did not get the larger heat exchanger...but I do know my numbers are good on the street when my car is hot.
Again, low from most other results I've read in the forums. But then if I had let the local tuner re-tune, I would have expected to be around 539 rwhp and 560 rwt...according to the tuner. Those numbers would be when the engine was warm-hot, so those would be pretty good numbers in my opinion.
Evo posts up to 145 rwhp gains with their stage II kit. I only recieved a 97 rwhp gain...which is about 2/3 of the posted possible gain. I was dissapointed at the increase, so I called Evo. I got hammered with a bunch of questions, i.e. type dyno, tire pressure, where the rear tires were on the roller and several others. In short I was told that they could not tell me why my numbers were so low. They just seemed to want to get me off the phone. I then sent an e-mail, but never received a response. Of course when I was interested in purchasing something, they were all ears and very helpful.
Now that I've complained...you still have a problem. Your car needs to be fine tuned for your vehicle. This is going to cost you more money.
1) You'll need to get your dyno results to Evo or Jon Lund (I've not heard anything bad about this guy) and/or some data logging. They will then attempt to refine the tune specifically to your car. IF Evo will do that for free, then you've saved "some" money. If you go w/Jon Lund, (and maybe Evo too), you'll have to pay additional money for the tune. It would be a shame for Evo to charge you since you already paid them $400 for a tune.
2) Then you'll have to apply the new tune AND dyno again...so you know your tune is safe. So you'll have to pay for dyno time.
3) If the second tune is not the best, then you'll have to go through the process again, which will cost more.
I suggest, IF you have a good local tuner, take it to him and have him tune it specifically to your car and have it done right the first time. You'll have a well tuned car right after and won't have to worry about sending dyno results or data logging back and forth...and the wait in between.
Just my 2 cents.
Go to the bottom of this forum and look at the similar threads...it will give you more info on other people's results w/Evo's stage II kit.
