RembaSS 1SG Posted July 29, 2016 Report Share Posted July 29, 2016 Hello All, haven't been on here in ages. Just to do research for the truck etc. Truck just went over 100k last weekend. About 45K on the SC, 408. I wished it was always running well though. Sometimes its just a PITA. Never was able to get it tuned fully. Goes Lean BAD at WOT. Dies at 85 mph (2600 rpm) on the toll road so I'm thinking its another fuel pump issue. This time I am changing out the whole module and not just the 340lph pump.
