I knew this was coming, I did a search after I posted this thread and found a plethora of information on the subject. :bangit:Not trying to be rude, but give the search function a shot. You will find more opinions on this subject than you will care to read.
I have been tossing back and forth as to which type of tuner to go with. For a while I was set on going with Uprev, but their customer service doesn't seem to be a priority. It's difficult to get answers from them, let alone a return e-mail.
They take care of their customers but its a small operation so it takes some time for them to respond SOMTIMES. At least in my experience and after meeting the crew i can see that they all know their stuff and what their doing. so good that even nissan is hiring them to put together tunes for nismo packages because they where years ahead of nissan in the aftermarket 350z world. My experience with the handheld tuners has been quite different. Hypertech particuraly will email you back right away but will give some BS answer for any problems you are having. Most of the time its some receptionist customer service person acting like they know the tech info . Hypertech blames the problem on anyone else and uprev will try and help you solve the problem. They even helped a member at a dyno meet that was using a bullydog programmer to try and fix the issues he was having with it in his truck. I would say thats going above and beyond. Ive been burned many times with handhelds and cant afford to replace any more motors
Just my experiences
No prob. thats what the forums are for. So we dont get hosed buying faulty products. As stated above anything more than a CAI and exhaust you will need uprev. Even with only those mods and a handheld i would feel better to at least get it logged once to make sure your in safe afr territory. I had a CAI with out a tune and was dangerous lean (first generation S&B filter).Good thing i had other data log software or i coulda done some damage. Also if the afr is too far off the ecu will try to correct and dump in exra fuel. My fuel milage went down to 5-9mpg at best before i fixed the probI'm sure that's true. I bet they get plenty of e-mails and phone calls, and have to spend the largest amount of time with customers who have purchased their product. I also was just relaying my personal experience.
