EFI Live or PPE seem to be the most popular. Both offer low to high HP gains and good economy.

Just depends on his needs.

it is just a farm truck. he is not wanting to have to do any transmission upgrades or anything drastic like that

Get a PPE Economy or Standard tuner. Keep it on 90 or 160 and go from there. Prolly the 90 would be good enough.
