Bully Dog GT Gsa Tuner
Hey guy's I just wanted to know is it worth it to buy this Bully Dog for my Maxima? Does it really advance the timing +2, removes the governor and gives you a full throttle after 100Mph?
Let me know because I don't want to throw my money away

Timing refers to the event when the piston makes contact with the spark plug in your engine cylinder, which is also known as top dead center (TDC) if I'm not mistaken. At zero timing adjustment, the spark will ignite when the piston reaches TDC.
Advanced timing is when the spark ignites before the piston reaches TDC. As the piston moves in the engine, air is compressed and such. +2 timing advance ignites that volume of air and fuel at a point where the compression allows for higher power gains. I'm not sure if this has to do anything with piston head compression ratings though.

Usually for naturally aspirated motors, advanced timing is benefitial. I do +4 sometimes which is actually still in the safe timing range for the VQ35DE.
For turbo and other forced induction motors, I've read that retarded timing, say - 2 timing, is actually better since the motor is being forced with more air to compress instead of relying on the internal piston chamber pressures.
Hope that helps. Anyone, feel free to chime in.

Sharper throttle response. A nice kick at low rpms and a definite harder pull in the higher revs. Definitely can feel more G forces with the +4 timing.
Can't measure the hp. But the butt dyno does show results.
Not sure if it'll work on older gen maximas. You may need to check their site.
Is it worth the money? For $300, its not bad. It's a decent and lesser alternative to the much more expensive UpRev.

Is it easy plug and play?

I have the wiring installed in my car. Just a plug into the OBD port and into the fuse. I tucked the wiring back under the dash so you can't even see it.
You don't need to keep the tuner unit always connected. I keep mine in the glove compartment for when I feel like doing a quick "reprogram".

In theory, could a piggyback like this advance timing at the lower RPMs, then advance it less as RPMs increase to get more power "under the curve"?

Nah.. timing is advanced throughout the entire powerband.
On older cars, timing is changed mechanically affecting piston position and spark ignition. I dont think it is possible to achieve multiple types of timing while the car is in motion.
The GT Tuner does not allow any multiple timing change over certain RPM ranges.
