I finally got my sprint 520s installed and have done some testing. I'm getting about 3 MPGs better with them and a quicker cold weather start. The PP520 car does have a little more pull in the higher RPM range (2500-4000) but both cars feel strong so I'm leaning toward the Sprints for my RC2 tune which is exactly what Jeff Robertson told me. The PP520s probably would be best for an RC3 or 4 tune but I'm not ready for the turbo upgrade yet. One thing I have noticed is that both cars are giving me shudder at arround 1800 RPM in 5th. I have the IQ at 6 on both so need some advice on what else to check. The timing is at 60 on both cars too. I didn't notice this in warm weather so it just may be the winter fuel causing it.
