Just seein if you had anything that would work well on my 4bt setup... I want it to get better spoolup, lower egts and better mpgs..... I know a lot to ask but if you have it let me know. My set up will be he341, 40hp injectors, on a ppump 4bt... its in a 5000# or so 89 k5 blazer 4x4 with a nv4500 tranny. 3.08 gears and 33 in tires. So it cruises at a very low rpm under 1500rpm. but i want to be able to spin it up to 3200 or so.
