JAK makes a fuel chip for the 33.9 lb per hr red top injectors however it's programed for a 3 bar fuel pressure regulator which is the way to go anyway. There are a lot of different red top injectors out there depending on where you purchased yours. One company even grinds the numbers off which makes it impossible to have JAK do the right fuel chip! Assuming yours have the original Bosch part number check and see just what they are before you go any further. My favorite injector is the 431 with the dual spray pattern which is the one JAK does the Classic chip for. The Ford 30 lb ones flow exactly the same on my injector machine but have the typical earlier spray pattern. I've used both in my '90 SPG ('90 1/2 Aero) and they behaved the same. The Ford ones are rated at 2.7 bar where the 431 Saab ones are calculated at 3 bar so the 30's and the 33.9's actually flow the same. I've got all the Bosch numbers if you need any help figuring out what you have? Dave
