throttle response & acceleration

jlask370

wanting to increase throttle response and acceleration on my Z thinking about doing a pulley kit NST or Stillen and looking at the sprint booster, before i get a tune any input or info is great thanks guys

Sprint Booster is an option you should consider. Use the search function and you will find my review along with other recommendations.

It really does work. I am very impressed.

I have an NST pulley, and I really like it. However, get a tune. Seriously the best mod you can get to help with it. Sprint boosters might but what you're really looking for but with those there's no difference between pushing the pedal past 60% or the floor.

I think the best combo for that would be a pulley sprint booster and tune. Dont k ow if an uprev can help as well. Does anybody have a DIY with a sprint booster?

Yeah you plug it in, goes between the pedal's wiring harness. UpRev can reduce the throttle lag/acceleration delay and IMO it's the better way to go.

OP If you're looking for cheap, just do the sprint booster. If you do the pulley you should also get a tune (UpRev or ECuTek).

What if you add a sprint booster then an uprev tune? Do you think it'll defeat the purpose of either or, or will it actually help?

All the sprint booster does is amplify the throttle signal. It'll feel peppier at part throttle, but WOT will feel like it's occuring at less than full throttle. For the cost of the sprint booster, you're well on the way to paying for a tune. Get the tune. It comes with other nifty stuff, as well as more power. Intakes can also improve throttle response. If you're going to get a tune, get any other mods you may want before the tune so you don't have to do it twice.

I'm not going to get into the pulley debate here. Many people experience good results. There is also the potential for serious issues. Do your research on that one.

Well said.

With sprint booster it amplifies the signal like stated. And what that means is that when you put your foot down 20% is outputting some higher number, lets just say 35%. That said, you'll get to a certain point where there's no difference between the position you're in, say 80% and the floor. Having the sprint booster is just like putting your foot down harder. Just try the tune first before you spend another $200 or whatever a sprint booster runs. I personally don't know anyone running a tune AND a sprint booster, but if there is someone please chime in.

This guys is running both which is why Im asking. I have already asked him. Just waiting on reply.

I think both would be quite helpful. The uprev would allow more power output while the booster would allow a faster reaction between your foot peddle and acceleration. As apposed to the delay.

UpRev's throttle remapping capability obviates the need for the Sprint Booster.

As other have commented, all the Sprint Booster does is tell the ECM that you are pushing the pedal farther than you actually are and remapping the throttle control with UpRev (or other tuning software/hardware) accomplishes the same thing. The upshot is that if you plan on buying UpRev, you really won't need the Sprint Booster.

You can adjust the throttle with Uprev. If you can press the gas a little more than you think you need, you've just replicated the sprint booster for free.

You may wait a while on John's response. He's away from his car, and there's significant tuning required before it's dialed in.

wheee!

I have a friend running both and he swears this is still a difference with UpRev and the Sprint Booster... He can definitley tell when the Sprint Booster is off and he has had throttle mapping and lag removed via UpRev too. The bottom line is, it amplifies the signal and priovides a quicker throttle response than your foot can deliver. No matter how fast you push your foot, the Sprint Booster will do it faster... with or without UpRev

He has sprint booster yes but doesn't have a tune yet. Plus he did an engine build, cleaning his heads up, changing the valve springs, exhaust camshaft is more aggressive as well. So it's kind of tough to compare a well built machine like his to a standard car that just has a sprint booster.

Edit: I seriously don't get why everyone is so afraid of a tune. There's hundreds of threads on tuning and tuning capabilities, there's also threads on sprint booster as well. Do some freaking research folks.

Yeah, his experience will not be applicable for the most part.
