Ok so i just looked at the EFI live site and i did see that I fall into the gen 3. Is there any thing you guys an tell me that might help like which ecm i might have. I see number thrown around like T43 is the the ECM, TCM or PCM #'s? The EFI live is something that i really want to get in to, I just want to know a little more before i buy it.

welcome :cheers:

yeah I'm pretty sure you have a Gen III, not sure what PCM exactally, someone running a simmilar truck might be able to help. all I can say about EFIlive is that its the best thing to happen to my truck, hands down. if you get it you won't regret it for a second. and everyone around here is very knowledgable and helpful, which makes learning to tune so much easier and more enjoyable.

Thank you! I'm really looking forward to start tuning. Any info or tips on tuning my truck would be great! The only bods i have right now is a K&N and the vet servo swap.

Get a Wideband for Auto VE and MAF tuning , and read , read , read , tuning is not hard just lots to consider .
To me EFILive was easy to learn versus the competitor , but that was me .
Download the Demo and have a look at EFILive : http://www.efilive.com/index.php?option=com_content&view=article&id=48&Itemid=133 and then read the Tutorials : http://www.efilive.com/index.php?option=com_content&view=article&id=130&Itemid=134.

You need a Wide Band AFR controller,
one that has a serial and/or analog output.
Most have a linear analog output stay away from the ones that don't
to make things easier.

I'm in Beaver Dam Wisconsin. Thank you for the warm welcome! I'm really looking forward to tuning with this program, I'm probably going to be leaning on you guys quit a bit at first while I'm learning the ropes.
