New Product Announcement - The Boost Box! Boost by gear for the SRT4!

[phrozen]

We may end the introductory pricing at some point, but we'll let everyone know before we do.

We are also working on the software to try and eliminate the tuning. Of course, we'll post that software for free for everyone.

The 2 settings is a big deal. HOM non HOM is a dramatic difference & the boost doesn't change.

[phrozen]

Not sure what you mean.... You shouldn't have to change your boost on HOM....

[phrozen]

oh, if you mean for traction... lowering boost while on HOM?

[srt4geezer]

Bingo!

i have done hundreds of pulls and spent hours tuning and have done everything john has told me to do. still nothing. Its never consistent. 3-5 is set at 18 and when i finaly get it to just hit 18 in 3rd ( it falls very quickly to 14) 4th gear will boost plum to 26 and hit boost cut. i have tried everything i mean everything. i know i have drove john and jay crazy. im not trying to complain the boost box is just not for me. will you please refund my money and i will ship it back.

I'm sorry you haven't been able to get it to work. As I mentioned in my email, I think you need to lower the preload on your WGA. I think it is too high. Have you tried that?

If you want to return any of our products for any reason, you can always do so within the first 30 days. Just pack it up and mail back to us and we'll send you a full refund.

I sent you our address in response to your email.

My car doesnt have a boost box on it, my car has the pcm out of the loop and spikes 23 ish holding 16ish to redline, and in fourth or fifth it kinda spikes to like 27ish (fully built ported stock turbo). Anyways my question is will your boost box cutout if i set it to like 23ish max or will it still give me full power just not let me go over 23ish (kinda like an external wastegate). And will this product work for me???

I was also under the impression that the boost box was your version of the electronc boost controller? You guys have both?

The Boost Box is an electronic boost controller.

If you set the overboost feature at 23 psi, when you hit 23 psi, the boost will cutout instantly, like you hit a wall. It will shutdown completely to save your motor. The overboost feature is there as a safety to shut things down if they are not tuned right.

If you tune it right, it should not spike like you have it now. It should only spike by a few psi and then settle to the target. How are you controlling boost now that you have such a huge spike?


The only other thing you will need is a 3 bar map sensor, if you want to make boost higher than about 17 psi. The stock 2.25 bar map sensor only reads up to about 18.5 psi, and you need about 2 psi of headroom for good control.
