I recently discovered this company Nisformance in NC that deals with Maximas and Altimas and some SPEC Vs, anyway they are offering shelf tunes for Naturally Aspirated bolted QR25s, 02-03 (Non Uprev supported ECU) for $250 or something, kind of like what TECHNOSQUARE used to do back in the day before the main ECU tech passed away. I'm seriously considering this option since it is less expensive compared to the UPREV conversion kit and all I really have are basic bolt ons, I've chatted with the guy on the phone and he seemed confident in their capabilities as long as you are running the stock MAF and stock injectors. Does anybody on here have any experience with these guys by chance? Give me some feed back on their tuning work if you do. Thanks!
