The turbo would simply spool up and the EGT's would not go over 1100 degrees - cooler by 100 degrees over the stock tune. It was very surprising to me how much better the engine sounded and ran as well. Bill knows his stuff and if I ever have a need for a another chip on a different truck I will not consider any other vendor. VERY satisified customer.

Just want to send a sincere thank you to you both.  I won’t go into detail about how amazing my truck runs now as I’m sure you frequently hear that (however I must say that it has far exceeded my expectations), but I did want to let you know how amazed and impressed I am with your service.  You took time out of your Saturday, on the 4^th of July no less, to help me out and get my tunes complete.  I can honestly say I’ve never experienced such commitment and follow-through from a business owner.

I will be your best salesman in Calgary and will be sure to send you as much business as I can.  Thanks again, sorry to have taken up so much of your time last weekend.

If I ever get to Georgia, I’ll be sure to stop in with a few cold Molsons for you!!!

It gets even better, Ice Storm last night in North Jersey so I had to use 4wd to drive home, drove an entire hour between 40 and 60mph with the 4wd on, and I was cruising most of the time around 19 to 23mpgs, unless I was accelerating and I averaged 15.5.  When I first bought the truck, I was averaging from 12mpgs with 2wd and a semi-heavy foot to 8mpg with 4wd.  I mean this is really great and Bill knows what he's doing, has anyone else seen improvements like this? I am shocked, I wish my v6 with 3.73s could get better mpgs.

Bill with your custom tunes, I think you should eventually tackle custom tunes for Mustangs and if you do, I'll be one of the first to try it and recommend it to my club of 570+ members.

Once again, I would like to thank PHP especially the helpful people who helped keep me patient.  Thanks and great work!

I wanted to thank you and your wife for your professionalism and service oriented attitude. The tunes you created for me are excellent! They canned tunes were impressive, but the custom  tunes really brought my truck to life. Like most people, I loaded the Performance tune first and I was stunned by the power. I usually drive like a little old man, but I really pushed her this week.  Normally I would use a half a tank a week, but this week I only used a quarter tank. That was getting "ON" it to boot.

A buddy of mine (poor soul, a Chevy driving lover) borrowed the truck one day, and he came back wondering what I had done to it :-) He was impressed and wondered if you do Chevys as well so I told him I would ask you. Either way, I think there may be some Marines from MCAS Miramar ordering Gryphons soon. I know I am saving ga$ with this tune. After this tank is gone I will be trying the Economy tune you created for me.

Take care, get some rest, and last but NOT least "Thank You" both.

I would like to start out by saying thank you to Bill & Corey of Power Hungry Performance! Not only is Bill a master of his trade but he and Corey are some of the nicest people I have ever had the pleasure of dealing with! In this day and age it is not very often that what is being sold matches its advertisement, and God knows you can count on one hand the times that the product ends up being superior.

I am actually traveling right now to a little league baseball district tournament in Ocala, Florida so this is the first tank of gas in a variety of driving conditions (stop & go to Highway) using the Gryphon's custom 93 octane performance tune and I can tell a night and day difference above the previous performance canned tune throughout the entire powerband.

I bought the truck for its towing ability to pull our travel trailer.  What I did not expect though was the throttle lag and sluggish downshifting when I wanted a sudden burst of power for passing.  Bill's towing tune on the Gryphon has changed all that. Now I have quick throttle response and crisp, sure shifting that makes passing, even while pulling a trailer, a breeze.  It's like I have a new truck at virtually no cost.

Additionally, since I can now monitor powertrain parameters like Transmission Fluid Temperature and Cylinder Head Temperature, I've gained peace of mind from knowing the level of stress I'm putting on the vehicle, especially when towing over high mountain passes.

Bill and Corey have been absolutely superb in the area of customer support. They are easy to reach and they clearly have the satisfaction of their customers as their first priority. Bottom line: A first class product from a business with integrity!  Power Hungry Performance is a winner!

I just received my custom tunes and new Pegasus software for the Gryphon.  I am extremely pleased with performance gains and mpg I am getting with my new tunes. Also, big thanks for the awesome customer support I received from Bill and Corey.  They are really class act people! A Big Thumbs Up!

I want to thank you for your assistance in removing the speed limiter from my truck. I had almost given up until I met you guys on the forums and started talking to you by phone. You guys were able to figure out why my [programmer] would not remove my speed limiter and sent me the updated firmware that removed the limiter.

Out of all the customer service people I have dealt with you guys were the best and most polite of all. I will recommend you to anyone that... wants their [programmer] custom tuned.

Again, I want to thank you and tell you to keep up the Amazing Work.

I just wanted to thank you for the tunes! It drives like a different truck now! 87 Perf. is great and I can't wait to try the 93 Perf[ormance Tune]!

My truck is better than ever!  Got custom tunes for towing and performance. The truck now pulls the boat and I don't even feel it. The performance tune throws me into the back of my seat and turns heads. Great customer service and walked me through step by step.

I cannot thank you enough for writing a tune to get my truck back to stock after someone else had reprogrammed it, and then for writing the custom tunes for it. I have been using the 87 Octane Performance Tune and can really feel a difference in how the truck performs and how much more drivable it is now!

Before your tune my truck was getting 8MPG on a different company's tune for around town driving, now I am getting 13MPG.  It may not sound like much, but it is a 5MPG increase just for loading a different tune.

I also wanted to thank you for your outstanding customer service and support over the weekend. It is not hard to see why your company is growing; you guys are the best!
