fellas,

I did a bit of searching and there was a ton of info on the Bullydog and Hypertech tunes but next to nothing on Uprev. after trying out both of the above i think its time to go Uprev. Mods are K&N drop ins, FI HFC and FI Catback. im getting hesitation in lower rpms when i get on the gas, im thinking all of this can be fixed with a tune.

Im looking for feedback on those of you that have gotten your G tuned with an Uprev tune. number gains as well as butt dyno and responsiveness. im in Houston so at sea level and temps arent too bad.

 

I have a canned temporary 'e-tune' from Uprev for high flow exhaust(due to time constraints with work, I need to go back for full dyno tune). They are the only game if you are serious. I had major hesitation issues at WOT, and all I have are RTP's and exhaust. It's totally fixed now and no SES lights. I didn't do the dyno tune yet, I will do that next when I can get time off work, it will be even better I am sure. Their maps for economy, valet, non premium fuel, etc are awesome too. Obviously I don't have any dyno sheets quite yet, but butt dyno feels pretty darn good!

All the serious race drivers are using Uprev and tuning as far as I know on their race and track cars. If you buy the 200$ cable, you can tweak stuff yourself from a laptop (and back up your rom, i.e. swap it out when you go to the dealer, put it back after you return).

Cobb got out of the nissan business, so AFAIK there is only hypertech and technosquare, very minor players. I haven't heard a lot of good things with hypertech either. Nissan changes their maps and roms so much, I think you need a place like Uprev that keeps on top of it all for the best results.
