Did you get yours yet?

Would be interested to hear your comments on what you think of it.

Not yet. It is in back order. I'll report back once I have it installed... Hopefully soon!!!

I finally got the sprint booster installed. Have to say this is the best $300 spent on the Z so far!! The pedal is very very responsive after the install. This is how the Z should be. I do have uprev before the sprint booster. I can say that uprev did helped a little on the lag, but the SP bring it to another level of responsiveness.

Highly recommended. The pedal feel is different than just floor your gas pedal!!

If whoever did your Uprev adjusted it correctly you wouldn't need the booster.:tiphat:

You would change your mind after trying it.

Baer383 before you say another word. Buy this device and install it. You WILL thank me. There is ZERO lag. And you'll know what I'm talking about when you give it a go.

I just installed mine,and anyone who says its snake oil does not have one, HOWEVER, at WOT my car feels "different" with the booster on, almost like my throttle is NOT all the way open, it is strange. I have been testing in different gears just say from 3k to 3500 in 5th gear, and the engine has a deeper sound than when the booster is on, I know it is strange but I know my car well, and something is amiss...other than that, OMG like a teenage girl, fixes the throttle lag on any non WOT situation, which is most of the time.

That's probably because the booster is telling the car to open the throttle all the way well before the pedal is floored.

I came to this conclusion as well, my first thought actually, but WOT should still be WOT, no matter how fast or slow it is pressed, I will continue my tests before I pass final judgement. I wish I had engine monitoring software so I could see the throttle %.

No it removes the lag that the factory settings has by a **** ton and aggressively tunes for increased responsiveness.

Wot is Wot. But the factory lag is removed and there is nothing that you can do about that regardless how fast you press the peddle down. And this is aside from a more aggressive responsiveness that this devixe gives you. Its a hell of a differece when both of those are combined.

When you redo the throttle maps in Uprev from scratch the throttle lag is removed,but most people won't take the time to do this but I have.:tup:

Right. But the side effect of increasing the signal by 30% means that the car will think it is at WOT at 70% pedal travel. The white paper showed it pretty clearly with charts of the throttle position and the signal sent to the car. You can't have it both ways. If you increase the rate the throttle opens, you reach maximum earlier.

I'll be installing the Apexi Version soon, I will keep you guys updated. I figured I would go with a company Im very familiar with and had great experiences with.
