Uprev tuning is definitely worth it! I had my Z dyno tuned with an UpRev rom as well as my Altima SE-R that I had a few years ago, and in both cases, saw anywhere from about 7-12 lb ft of torque gain across the ENTIRE rev band. And if you're seeing even 10 lb ft more at 7,000+ rpm (or roughly where our VQ37's are peaking in power output), you're looking at 13+ peak whp increase. IMO though, the best part of the uprev tunes is what the tuner has been able to get out of the midrange. The engines just feel so much more lively from 2-5k! All in all, I've loved the uprev tunes and feel they've been worth every penny!

Don't expect it to work magic for your throttle response, but depending on what ROM you are running currently, whatever updated ROM the dyno shop flashes onto your ECU may have updated throttle tables that could help it out.

When I had my Z dyno tuned towards the end of last year, the shop used the latest ROM and I've never had any issue with my throttle response. It's quite good.
