    I noticed today coming home my truck would occasionally jump in rpms only like one tick on the tach but you could feel it. No cruise, and would do it in any gear and speed about every 30 seconds. First thing I am doing is draining the housing of the filter, going to replace the filter then go...

    Hello, I'm hoping that someone can help me figure out what's going on with my truck. I recently replaced the power steering pump and after doing so I now have a lope at idle. I don't believe there is a connection with the pump but I may be wrong as I did move the airbox and I could have caused...

    Not sure where to start so - I have 30% over injectors, less than 50k miles old from Exergy (truck 280k) tuned with a RaceMe Ultra on +60hp tow tune. During the summer months, if I ever did a hard pull I would get a CEL with code: P0087: Fuel Rail Pressure Too Low. Back then I would think...

    Like many things in life during 2020, we had pump sourcing issues with our Fuel Boss pumps. The supplier consolidated and the pump was discontinued. However, in November 2020 we found a comparable pump. We spent hours testing the new pump on a 1998.5, 2nd gen and on a 2007, 3rd gen. Both tests...
