Hyperpac LBZ

[Unit453]

Ever since I got my EGR valve replaced under warranty, my Hyperpac wouldnt communicate with my ECM. GM installed the latest cal updates. I contacted my buddy from Hypertech, Darnell, who offered to take it back, reprogram it for the latest updates and return it to me. I received it back 4 days after I sent it to them to update it. I'm pleased with their customer service and support. They went outta their way help me out with this.

So I tuned it yesterday, and made a trip up to meet with a local member to have him sign the oil can. I forgot how much I liked their tunes. Its got a very defined throttle position to where it'll start to shit and get. I definitely drive it harder because the throttle feels different. I'm not sure what it is about the tune but the engine is so much throatier now than before with the Predator. Its got a deeper tone to it that I really like. It also smokes more than Predator does.

I was monitoring the live data that Hyperpac's capable of and I noticed a few things different from my previous northern NY climate.

My fuel temps were hovering at around 115. I dont remember seeing them that high. Outside air temps yesterday were between 75-80. It was 77 when I was monitoring the data. I was also on the highway, cruise set at 75. My air intake temps were around 100 degrees, which I thought was a bit high considering S&B is supposed to cut down on sucking in hot underhood air. If I gave it throttle, those temps sky rocketed to 150 degrees before I got off it. The stock intake did exactly the same, especially with the PPE air box mod. Even at idle, the intake air temps were a solid 20 degrees warmer than outside air temps.

Fuel rail pressure was hovering at around 14,000 and some change PSI at 75 mph.

My trans temp pretty much stuck right between 145-155. I remember driving to work up north, it wouldnt even break 100, with the winter cover on. I've seen 200 in stop and go traffic here so eventually, I'd like to get a Mike L. trans cooler.

Hyperpac also showed my torque converter at 65% lock at 75 mph. I was under the impression that it locks at highway speeds or once in 5th?

32.25" got my speedo right on with 285's. Looks like I'm gonna be running this tune for a while now. Thanks to Darnell once again for excellent support.

Good write up Nick. Been wondering how Hyperpac ran since I don't hear a lot about them.

Good to hear Nick. Hows the shifting ?

Darnell helped me out when my PPIII wouldnt communicate. They have great Cust. serv.

The power was great towing and driving around but i never liked the shifting.

Sounds like they got it Figured out.

My shifting is great. Predator tends to short shift, much like Fords do from the factory. Not just diesels, all Fords short shift. It supposedly saves on fuel mileage. I never realized it until I throw in a Hyperpac tune and roll it, do I then feel the differences in shift and shift patterns. Its smooth as smooth can be at any and all rpms. I actually get full boost at half throttle so I no longer really need to get in it to be able to scoot away. It does take very little effort to get it to down shift too. Its different and I like it. Predator wont let you unless you bury the throttle, and only then will it downshift. Normally, it'll allow you to roll into it in most gears. Hypertech downshifts and gets you right inside the power band. They also did an awesome job at getting rid, or cutting down the turbo lag. There's way less lag on this LBZ than my LLY had to begin with. I noticed that right away but its still there and just the nature of the beast I guess. With Hyperpac's tune, you punch it, you go, plain and simple. There's no waiting around. I really like it.

I will say though that the motor's definitely throatier. I dont know why or how but the sound is deeper, and that, I really like.

 

[TIM Z]

Cool.

Glad your still liking it man.

Great post Nick.

That sounds like a really nice tune. Is the Hyperpack easier or harder on the transmission compared to the Predator? How expensive are they?

Do you have a TransGo Jr shift kit in your truck?

 

[Unit453]

Bone stock trans Ray. I would think its harder on the tranny but really have no idea. Sometimes it feels stronger. The predator made the throttle so much more sensitive. Either tune isnt good for any stock trans. I dont drive it hard though so I should be alright for many miles to come.

I'm not sure what the Max Energy's are priced at but I run Hyperpac, which is their live data. Thats around $600 if I remember right. It isnt cheap but it does some cool stuff.

Nick, I'm glad you like yours...I hated my HPPIII. The shifts were terrible on all levels no matter how I let the trans learn. It defueled badly and the 2200rpm sudden power increase sucked. I found nothing smooth about mine. I called Hypertech customer support and ask if there was anything I could do to smooth it out and was told "no one has ever said anything like that about our programming" then basically told me there wasn't anything they could do.

I suffered thru almost a year and took it off and got the Predator. I don't have a touchy throttle and the trans shifts like it did stock with no programmer.

I guess I'm not the lucky one to see increased mpg as neither programmer increased my milage. Actually I got worse with the PPIII.

I think I want to try EFILive as the programmers aren't giving me the increases I'd like, performance or mileage

 

[Unit453]

My mileage with Hypertech is no where near the Predator though. Thats the only bad part that I dont care for.

 

[trotorx2]

I have a 600 mile trip tomorrow, I may take the HPPIII and try it again.

Nick, how did you get them to reprogram yours?

 

[Unit453]

I contacted Darnell @ Hypertech and he gave me instructions on how to update it. It was totally useless to me with the latest GM software update. Quick turn around too. I sent it off and had it back within 5 days or so.

Do you need contact info?

 

[trotorx2]

I took it out to try to install and it said it couldn't find the cal and had a code 6D and to call Hypertech. I guess mine isn't any good now either.

I guess I could PM Darnell over at the other place and ask about it then at least I could sell it.

Feel free to PM any info you want to pas along.

Thanks
