I was looking around one day and found this scan tool: http://www.digimoto.com/ I'm wondering if this tool would let me log enough sensor info to send to Lyndon at Westers for a tune more for my specific engine. When I got the tune from Lyndon I didn't know about Allen over in San Antonio and I don't have access to a dyno. I really don't know how to tune these new pcm controlled trucks and I think my latest tune needs some fine tuning. If any of you tuners could help me out with this I'd appreciate it.
