The GIAC seems to be the top HP provider but at a $1000 premium offering 1.3 bar and 100 hp. Wastegates not needed.

You will never get 550 w/ out upgrading the turbos (whp, not ***** fwhp). Do this, pick a tuner, get the flash and just make sure you have the option of upgrading when you learn how limited stock K 24's are.

 

One more interesting question for your list of questions. Does the tuner allow you to sell the flash to a third party (e.g. if you sell the car and want to return it to stock and sell off the mods)? This was important to me when I was researching and only EPL would allow me to do so.

 

I think there are a lot of good vendors, and your original list seems comprehensive of the good ones.
I went with EPL because of price, proximity, customer service, and incredible testimonials offered on this site.
I feel I chose wisely as I have nothing poor to say about the transaction, support, and results. As far as I'm concerned, EPL=FTW.

 

I think you should take a ride in several cars that are differently modified. I know there are several modified turbos near your area that could provide better picture for all your questions?

 

I had an Upsolute flash and was very happy with it. No problems at all. My K16 car dyno'd 407 hp and 430 tq on a Mustang dyno.

 

Here is my X50 (same as S) with GIAC. Upgraded wategates make a big difference.

 

I had the Upsolute k16 flash and then upgraded to the k24 flash when I changed my turbos. Unfortunately, no graphs to share but happy with performance, service and price.

 

Judging from what you wrote, EPL would probably be your best bet since you want to go Meth Injection. Tony and EPL seem to be the tuner with the most experience going that route. So that being said, you're going to have to have your car tuned for it eventually. With EPL route, it'll be an easy transformation when it comes time to upgrade, you'll just upgrade and Re-Tune as opposed to getting an entirely new tune. In my opinion, that makes the decision quite easy unless the other tuners are doing meth injection, but to my knowledge I don't think they are.

 

I love a good research Q&A thread as much as the next guy, but I actually agree with Dr Jitsu here..... major case of analysis paralysis!

 

Whose Wastegates did you use?

 

Flash,

How is that Camaro comming along? I see you have some nice dyno results.

I second the EPL suggestion since Tony will give you the option of future custom tunes. I am suprised no one has mentioned Protomotive...it seems Todd is not mentioned much around here lately.

 

I had a custom made Upsolute flash for K16/24 turbo's for 1.2 bar
After few months exhaust valve melted away,bent rod,scratched cilinder and piston,13000 euro paid for the repair,sended a few emails to Upsolute but they never answered me
Sended the flash to another programmer to investigate and he told me Upsolute raised the parameters for knock detection so high the computer didn't detect knock anymore and also the other parameters were raised very badly,but Upsolute programming was very cheap..

 

Well that makes you think twice about them. Thanks for the info..

 

out of the ones you mentioned narrow it down to the ones that will provide you a more customized tune.

As for Hp claims, that is all they are is claims. Looks at how fast cars have run with stock turbos and a tune, and go from there.

search is your friend.......lots of info on this forum if you take the time to do a search.
