Doing a swap on my 2007 Tahoe long tubes 3 inch duals e85 flex 5.3. Going with lsa blower and 2.50 pulley so around 10 lbs. Stock lsa injectors e38 ecm looking for some one willing to get me started with a good base tune to go from. Using the lsa map so been reading about rescaling and all this stuff just don't know enough about these to know I wil have a safe tune to start on. Any help is appreciated.
