I am going to buy a new used truck and it has a TST Powermax 3 already. I have an EZ an am very pleased with it on my truck. Would I be better off to sell the TST and put in an EZ and 275 injectors with the money, or is the powermax 3 a nice unit? Also, I know I am beating a dead horse here, but does ithave timing? Thanks, JOE
