I was waiting for the Race Chip to be released and I ordered it on the 15th of March. I had some delays in getting my order but Tim Gruber from day one has been outstanding and I will probably give a longer full review of the whole ordeal but all I can say is BUY IT!
If you thought you couldn't love your Stinger any more you are wrong. Install this in 15 minutes (10 of them just waiting per instructions). If you enjoy driving your Stinger "Normal" or if you DO NOT enjoy pulling up to a light and telling someone in a Mustang GT or SRT8 (forget about a regular BMW 335i or G37 too slow) nice car! Is it fast? And they look at you like you are an idiot in a Kia but when the light changes and they are left behind and they try as hard as they can and you walk them they get mad! Then you probably don't want this.
Keeping in mind I have the AWD and it's been rather chilly and rainy in GA lately so it's not exactly fair but what is fair considering they are mostly V8's. But when conditions are right the Stinger on paper is a little slower until the RACE CHIP. Don't waste your time or money with the lower levels get the GTS Black. If you are afraid when you press the accelerator that your KIA will blow up do not get this because it will scare you.
If you are scared of anything of the unknown just stop thinking about it and asking dumb questions about things like tuning and the reputable companies themselves. You may be stupid but don't show it. Do some research on these products, the companies, their reputations, please ask questions to the more informed posters and the manufactures and tuners/installers but stop with the "how does it work" , "it's just snake oil", I'm not going to directly quote some of them not to hurt their feelings and realize people go to forums for various reasons but please read and educate and experience things instead of wasting peoples time with stupid questions. Whoever said there is no such thing as a stupid question is wrong. Anyway I do not have 0-60 times, 1/4 mile, any dyno, or have not even used my torque app set up to compare before and after because I don't need it. What I need is something I can feel and you can feel this. Not just a "seat of the pants" dyno either.
It cracks me up all these people spending $400 for an intake and $1600 for an exhaust (do I wish my Stinger sounded more like my BMW X3 M40i in sport plus mode yes but it probably never will) that's $2000 and your car is much noisier and you get maybe 30hp and 30 pound ft lb and if you have a problem how are you going to take it off every time you visit the dealer. There is one guy out there taking off his whole exhaust to get 400 hp and it sounds like shit. Do not get me wrong I appreciate these risk takers on any new platform who push the envelope and show how far you can go before it breaks. I have modified many cars but always after I had many choices available to me and got much feedback from the early adopters.
Then you learn the week link in the car itself. If you are thinking about this spend the $800 and you will love it. If you don't love it you can sell it here or other forum for probably $600. When I have time I will post some hard numbers for people who really need them but for those who just need some encouragement order it today. Do not get the lower levels. If $200 or $300 more makes or breaks you, you probably shouldn't own a $40,000 to $50,000 car.
If you really can't afford it wait and save for the GTS Black. Also I do not work for Race Chip and I paid for mine. I did receive the $100 Forum discount after I placed my order which shows what a great company they are. Can I or anyone guarantee you will not ever have a problem with your car? No, but Race Chip is a first Rate Company and KIA makes a great product. I have had 5 Kia's and driven the shit out of all of them and never had major problem and minor things were fixed without any issues under warranty. When I mean driving the shit I mean maintaining the vehicle always but literally pushing the car whether driving my 2012 or 13 optima SX 155mph to top speed ( couldn't believe it )or pulling a trailer in my Soul ! or Sorento SX while driving to high rpm's all day.
I will try to update after vacation on true results.
