throttle response & acceleration

///PureSwank

I don't think anybody is afraid of a tune. As a matter of fact I think a tune is awesome because it extracts more power. My deal is figuring out wheather a sprint booster and tune would compliment each other rather then defeating each others purpose. I have heard that a tune doesn't remove as much lag as a sprint booster but will bring out more power, which is why I bring up this question. Would they compliment/work with each other or not.

Get the tune first, and then see if you want more response than what you'll get through the tune.

Then buy both and find out.

Sprintbooster

OP of that thread had one with a tune.

Or just switch to a cable throttle system.

I'm getring both regardless I just wanted input before hand. I'm still waiting on parts to come in so dyno tuning will be a necessity either way. I'll install booster after the tune and see if there is STILL a difference. I'm sure there will be. Hope they compliment each other.

Sounds like a plan. I'd say worst case scenario is you won't notice the difference I couldn't see how they would produce a worse response when combined.

A little research will answer your questions. The FSM has a good description of how the stock system works. You should be able to find out what the booster is doing from the manufacturer (website, manuals, &c) and/or reviews. Read through the topics on this site and others about remapping the ECM for better throttle response and using boosters.
I don't have any personal experience with either remapping or boosters but here's what I found on the Intertubes.

As far as I can tell, you can do everything with remapping that you can with the boosters. Ie, if you adjust the map via UpRev or other tuning software, the booster is not needed.

You could set things up so that the two complemented each other but that would just be making things needlessly more complicated since remapping alone will do the job.

YMMV

Don't know if you have a 6mt or not op, but if you do the best gain you will get or throttle response and acceleration will be through a lightened flywheel/clutch combo and you will rev like a motorcycle with quick response unlike the slow lumbering double blipping required with the stock unit.

6MT

Throttle response will be much better with an A/F ecu tune.

I have a sprint booster. Love it. When the setting is in race mode (red button), it is night and day difference between that and stock. The throttle is so crisp, maybe even too crisp. Did it make the car faster? No, but it definitely made it more responsive. And no, its not the same as just pushing down more. Our throttle's have this dead spot when you approach WOT. With the sprint booster, you don't have to approach that dead spot to get the car going.

Well said. I totally agree.

Sprint Booster works as advertised. I also maintain it in the Red setting. As a matter of fact, I have pulled the change cable altogether. Pretty cool this allows you to do that!!

Sprint Booster does change the shape of the curve, but keep in mind zero is still zero, and WOT is still WOT. Everything that happens between *is* a function of your foot, and you can make the car do the same thing by adjusting your foot. You may prefer the curve you get from Sprint Booster because it makes things feel more natural for you, but it's not doing anything you can't do manually.

UpRev tuning is mostly similar. It's very very slightly better in that you can also open up true WOT at low RPM (which the ECU normally limits a bit until the revs get up more, but that's in the ECU, Sprint Booster can't change that), but the value in that isn't huge.

In both cases, keep in mind that every change there comes with a tradeoff. The curve still has to start and stop at approximately the same values it did before. If you make one part of the curve ramp up significantly faster, there has to be a flatter area elsewhere to compensate.
