Hi guys, I'm thinking of tuning my car to improve it's performance. The two which I'm considering are:
1. Hypertech Max Energy Power Programmer Max Energy Sport
2. Bully Dog Triple Dog GT GAS: Gauge Tuner GAS

Which one is the best in terms of:
1. Performance (HP, Torque, 0-60)
2. Ease of Use (Installation, Return to Stock)
3. Problems?
4. Cost

I know the Bully Dog is not only a tuner but also a digital performance gauge. That's a neat feature to have. Has anyone had experience with these, specifically with the Bully Dog Tuner?

 

I forgot to ask:
1. Does it void warranty?
2. Improve or decrease gas mileage
3. Affect reliability (tranny, engine issues, etc)

 

there at TONS of threads about both these tuners that will give you everything you need. Check out the advanced search feature

 

I would also look into Uprev

 

Yes I've heard of Uprev, but it's done through a dealer. I was looking for a DIY installation.

 

Uprev also has the option of purchasing the cable and doing it yourself, there's the standard version where you upload etunes based on your datalogs and the tuner version that lets you fully tune the car yourself.

 

I found the UpRev Osiris ECU Tuner for 370Z/G37. It's cost more than I wanted to spend.

Is the Bully Dog Triple Dog GT GAS not good?

 

No one really uses it for the VQ'S.. If you had a titan that would be a different story, lol.

And you don't need to pay full retail, and especially not for the tuner edition. You can get standard brand new for 450

 

No one uses what? I found a Bully Dog Triple Dog GT GAS on Ebay for less than $300.

Why not? It doesn't work? The website says it's compatible with the G37.

 

All those plug in tuners are crap....at least for these cars. All they do is up the timing and fuel. No way to accurately monitor a/f ratios which is where theses cars will make their power with. Spend the extra money on a properly tuned car with Osiris Uprev through a licensed dealer and dont waste your money on the plug in ****. IMHO

 

I bought a Hypertech used for cheap and I like it. It did not make a night and day difference but it did improve responsiveness on my 08 G35 sedan. For $220 that could be re-sold in the future I say its pretty good.

 

You don't need the Tuner version unless you plan on tuning yourself. The Osiris standard version w/Etune for your noted modifications is all you need. It also includes the Cipher cable which is used for data logging and updating tunes. We are working on a Dealer agreement and will be offering packages here very shortly.
