I've always sworn by actual dyne-tuning vs. anything mail order, but the reviews from some of the hemi-fever stuff seem to be worthwhile. It appears he's willing to make tweaks as needed. As long as the customer service is there, I'm willing to try it.
It sounds like you order a diablo tuner and then he will load or send a program file to load onto the device and then flash it into your car?
The only thing I really plan on doing to this vehicle is maybe a CAI. I won't put headers or a cat-back on this vehicle, but if I can get a nice power increase and a shifting performance increase that would be a plus. Going from 365 factory to close to 400 would be nice.
Long term plan is to sell for an SRT, but that might be a couple years.
Thanks for any input.
I have the Hemifever tuning on my 2011 Hemi and love it. In fact I had to restore the stock tune 2 days ago to get some service done and couldn't wait to get home to upload the HF tune. Easy and simple process.
Sean with Hemifever is awesome. You'll get the tuner and he will have you log certain data points. You then send all this back to him and he modifies the tunes and sends you an adjusted tune for your specific vehicle. Great customer service, and if you're going to get a tuner I don't know why someone wouldn't use HF.
One of the biggest improvements I've noticed with the HF tunes is throttle response is much better now.
I've had my tune in my Jeep for 3 years now and haven't had any issues and just rolled over 81k miles today. would absolutely recommend it.
My newest conundrum is do I keep my Jeep and order an E63 Merc or trade the Jeep in for the Trackhawk?
