just looking for some options (MPG's)

[hayjayhorses]

I put reman single shot 90cc injectors in my '00 550 I went from 7.5 mpg to about 10 mpg, hauling hay. The over all power is about the same, more on low end and a little less after 2500rpm then the stock split shot 140cc.

I have not got it chipped yet (I will after I swap out the auto for a 6sp) so it idle like a big cam gasser.

as for the exhaust brake I have rigged up my exhaust back pressure valve on all my manual trans truck and run them with no issues

talk to Cody about tune with single shots
