I ordered a boost master, chip and heydon fan clutch from Bill Heath Diesel after a long talk with him. I installed the stuff this weekend and am very pleased with his service and his product. I can really tell a difference in the performance. I ordered the stuff on Thursday and received it Saturday with complete and very well written instructions.
