Delberts 5.3, DBC, COS3, 01270003.tun Here is my tune. Injectors are Bosch Blue Top 160lb low impedence injectors that I use a resistor to run. Keep in mind I already have another pcm with an HPtuners tune in it and the car idles, and runs great even with resistors instead of a driver box. I just can't tune it myself with HP because I own EFI live. My current pcm is also a 0411. The specs are in my signature but I am sure the pulse, IFR, etc... is not correct. With this tune it will start but only runs for a few seconds. The Main VE table in this tune is 30% less fuel than I started with but that is how far I had to drop it to get it to start.

Thanks for any help....
