there are nothing but good things to say about Jason Heffner. His products are AMAZING, his customer service is top notch, he answers his phones, or calls you back promptly. He has the most beautiful designed system, and by far the most fairly priced. two huge :thumb: for Heffner's Performance
It's no secret that I support Jason Heffner 100%. He puts out some of the fastest, highest horsepower, and streetable Vipers out there. He engineers excellent solutions for many of the problems that Viper owners face. Not only does he place a lot of emphasis on quality and performance, but his work is truly mechanical works of art.
I have had dealings with some other Viper tuners and Jason is by far the most talented and honest one that I have met. That's why I keep going back to feed my habit.
I would have to say with all the research I have done regarding the art of supercharging a Viper, that Jason Heffner is THE MAN! He has engineered a system that blows all other tuners away in terms of craftsmanship and efficiency and value. Jason Heffner's supercharger systems make MORE POWER with LESS BOOST for the best part of all....... LESS $$$$$$$$$! While another tuner is making a claimed 850 RWHP on 15 PSI. Jason takes the "safer" approach on one of his customer cars and makes a whopping 787 RWHP on "only" 8.82 PSI. I find this to be very impressive to say the least. In due time, there will be a tuner that will emerge as the undisputed KING of supercharging the Viper..... and his name is Jason Heffner!
P.S. Jason Heffner has also fabricated a twin supercharger system for a Lamborghini Diablo==> Can you say "Work of Art"?
Jason is a talented professional and great guy. I now have over 5000 trouble free miles on his "575" package and the car is now being upgraded to the 650 package. Jason gets my highest recommendation.
Meet Jason and tour his new facility for yourself. Viper heaven my friends.
I have a Heffer 900SCI package on my Viper. The system is best described as pure mechanical art. The highest quality goes into each weld, each bend, and each custom fabricated piece. The best parts are put in and there is tremendous attention to detail. All put together the car makes 775rwhp for a price that is THOUSANDS less than other competitors. Jason Heffner stands behind his products and provides excellent customer service. Truly a world class exotic car tuner.
100% Trustworthy Tuner! Jason gave me exactly what I wanted in my SC package, with potential for more POWER when I want it in the future!
Perfect install,clean with detail! Chromed was my choice!
Price was right, and the customer service has been top notch!
Thanks Jason, I'll be back!!! :thumb:
Some words of caution, if you remember the feeling of your 1st drive in your Viper! Yeah, that POWER that was so addicting! Well, that ain't SHIT compared to how addicting a Heffner SC'd Viper is!!
If you're on the boards regularly you know that Jason Heffner modified my car with his "575" package last year--and that I've been very happy with it. Recently, I asked Jason to upgrade me to his "650" package--with a minor twist. I asked Jason to focus on maintaining drivability--even if that cost me some horsepower. I live in the Washington DC area, drive the car in traffic a fair bit, my wife drives the car, etc., so I requested a milder cam.
Jason delivered on time and within cost--as always--and did exactly as I asked: gave me a very drivable car with more power. However, after driving the car a while, I regretted not asking for a more aggressive cam. I asked Jason if he could upgrade the cam a bit and still keep the drivability.
I picked the car up earlier today and found it to have smooth idle and acceleration and to be essentially as driveable as stock. I also have dyno sheets proving 571 RWHP and 578 RWTQ corrected to 556 and 563. Now here's the amazing part: no charge for the rework. Jason simply wanted me to be happy.
Don't know about you, but this kind of customer service doesn't happen much to me. Thought you all should know.
Jason worked on all three of my Vipers 01 GTS, 01 ACR and 03 SRT. I WILL NEVER TAKE MY CARS ANYWHERE ELSE!!! Jason knows his stuff and his work on Vipers is AWESOME.
I have been quietly researching the Viper industry for almost 2 years now and it is no accident why I chose Heffner Performance to be the tuner I would give my full support too.
It was a great honor to be invited to join Jason and team and help build something that I believe will be truly special.
I see an awesome future for Heffner Performance and am very excited to become part of that.
Simply the best tuner for viper. I would never let any other tuners work on my car. His turbo and supercharger systems are the best. Also, Jason works on all the cars and he tunes all of them.
So here's the deal. I see a lot of guys going on and on about how their tuner is god and things are just perfect. Then I meet them in person and they say, "Well there are a few things I'm not happy with, but if I say something it will put me in a bad spot." Let me tell you, I am not that person. I dropped the car off with Jason and 8 weeks later my car was back home with more power than I can use. I have heard horror stories about cars staying at the "other" tuners shop for 6 months, 8months, on up to two years!! Give me a fucking break!! Everyone on this board would have headr about that if it would have been me.
The bottom line is, Jason builds one strong ass engine. I have put a couple of thousand miles on it so far, and the car has performed flawlessly. The great thing is, if I ever have an issue, I know Jason is the type of guy that would jump through hoops to make it right. I can't imagine someone doing a better job than Jason Heffner.
what are his costs for his different stage TT packages? his website only says "starting at $30K" I am leaning toward TT instead of N/A, thinking that I will tire out of the mediocre hp/tq gains. Anyone in Chicago area with a Heffner TT?
