I just saw an ad for this "Sprint Booster" but I didn't find much during a search of NICO Club. Just wondering if it's worth all the money? http://www.sprintboosterusa.com/

It's not worth it. Please don't waste your time buying any of those "performance booster" or "performance chip" crap off the internet. The only way to get a true performance increase on your Infiniti is to get it UpRev'd.

there are other chips and tunes available "get a true performance increase" OP has cobb and technosquare as well as gtm.

the sprint booster is not something you want to buy for your infiniti.

I don't know of anyone who tried it, but I know I wouldn't.

I'm not sure how it can address the lag of the electronic control system. And at $300+ a pop, there are better and proven upgrades available out there.
