Well, goodbye to narrow band tuning and hello FAST wideband&#33; It will be here Saturday and I&#39;ll start tuning the 2007 4.8L for fuel mileage on the highway. Now to read up on the real time tuning. I&#39;ll tune the 93 with it too but I am going to start with the new truck to see if I can squeeze a little more fuel mileage out of it. It will be interesting to see if the factory tune is maximized or not. :rock:

I cant get RTT to work on my 04 or 02.....but awsome software...you will love it.All you can do is play with it alot and read on the forum :rock:

Im getting my LM1 this weekend

Well, hooked up the FAST wideband tonight and made some WOT runs. My readings at WOT are 13.3. Isn&#39;t that way too lean for full power? BTW, this is on the 2002 PCM&#39;d LS1 engine in the 93 truck, not the 2007 4.8L.
