A sprint booster is a cheap shortcut to the throttle response issue and is an apples to polar bears comparison to a proper engine tune.

You get a lot more out of a proper tune that will help your car run better for longer (assuming a good tuner), such as proper AFR and other misc adjustments your tuner can make. That's totally aside from the RaceRom features that Ecutek offers like mulitple custom tuning maps for various needs, launch control, and custom traction control.

:iagree:

I think everyone here is missing the point. This is clearly a gateway opportunity to the mod-bug-addiction.

OP - might as well get Intake/Exhaust/TestPipes/Turbos to go along with your tune.

First, you don't need to explain to me what a tune can do as my car is tuned.

Second, you're right: a Sprint booster IS a cheap shortcut... that's the point. As I said: "If all someone is after is throttle response then I'd recommend following dboss' advice and purchasing a used Sprint Booster for ~$150-200." Someone who ONLY wants increased throttle response and is leaving the car stock most likely does not need/want various tuning maps, launch control, blah blah blah that RR offers. If they do, they're probably not going to leave the car stock for long therefore what I said wouldn't apply to them.

No negative tone was intended brother :tiphat:

You are absolutely right. If throttle response is the only thing you're looking for, then the sb is a great budget option. I was just trying to make the connection that throttle response isn't the only thing that a tune on a fully stock Z (thread title) addresses :twocents:

We have to distinguish “throttle response” vs “throttle control”. In this case, sprint booster magnifies throttle input, whereas a tune allows for more precise throttle control.

If one desires to be able to manage extremely minute throttle change AND need immediacy, tune is the way. If one merely wants the feeling and perception of more urgent throttle, Sprint Booster will do just fine.

Agree, Sprint Booster gives quicker FULL throttle but less control.



Anyway, I wouldn't tune a stock car.

I would although I haven't, a sprint booster doesnt do it for me.

There is some throttle lag programmed into the ECU. This can only be eliminated by reprogramming the ECU (ie, a tune).

A SprintBooster does exactly the same thing that you can accomplish by pushing on the pedal a little harder. It does nothing to eliminate the lag in the ECU. Plus, as mentioned above, it decreases the control you have over the throttle (takes less movement of pedal to reach WOT).

If you have a SB and you like it then that's great. But it is not a substitute for a tune.

If your car is close to stock I would say don't tune it. I would keep the warranty in tack if you have one. I saw no need at all even with a Fast Intentions exhaust. If you do an intake and exhaust then I would think about getting it done. 3 Mods, you need it for sure. The 3rd mod would be test pipes, HF cat's, or long tube headers. Stock, it's not worth it to me.
