99 cummins injectors

Don, Can you send me a price on a set of Mach 4 ( I guess they are still considered 150's). Tried to pm you box is full. Thanks Johnny

The 4's have been redesigned, but are not quite ready to sell. I think 1 month should have them good to go.

They are so good I cant even describe them. The smoke is soooo low and the power is sooo smooth it is just crazy. They smoke like an RV275 at mid throttle, but can pour a little black at wide open, but it clears very fast. Fuel economy is up over the older Mach 4 too.

Thanks for the info, I will hit you up in a month or so. Can you pm a number to reach you. Thanks

any new info
