Looking at phoenix chip have ?'s
Hello all I have a early 99 truck with auto trans and am looking at getting the phoenix chip. Computer code is xle4. I tow a 10,000 lb fifth wheel and sometimes pull a 4000lb boat behind it. Thinking about the following tunes.
1-stock
2-25 extreme tow
3-40 heavy tow
4-65 mod tow
5- 80 dd
6-100perfomance
Are these good choices for the early truck? Only mods are 4" exhaust and 6637 airfilter. Currently running Superchips 1705 programmer. What differences/ improvements can I expect to see running PHP tunes over the Superchips? Any changes I should make on my tune selections? Thanks.
