looked at a lot of them and seems like the best.
chasing fuel leaks and changing filter faster, relocate the FFM to fender.
for a better connection, do the battery bolt mod.
was really surprised you decided to go electronic.
love the 2 piece crossover. would make it easier to mess with.
truck looks great and runs even better.

Thanks. Yea I put stronger gears in it and has held up fine. 4l80 takes a lot of power to drive. I didn't want too lose that's much power. I went electronic because at the time I could get the most power. Now their building pumps that run like garden hoses. It's nice though with cruise and high idle.

I took all under hood wiring, wiring for the computer that was in the glove box and the wiring for the pedal. I think 96 was kind of interim year for OBDII, right?

So looks like you must be right. All vehicles made after 1/1/96 had OBDII. I wonder does that make it more complicated or less?

I'm just following thru this build that Marv sent me and wanted to clarify a few things since i'm the 6.5L nut.

The oddball injection pump was in 1994 and has DS4-5068 on the label. It's an easy fix in the PROM chip to swap that pump onto any year 6.5. Easy is a term relative to me since I can do the tuning.

Don't let any years of the 6.5 electronics scare you away. I can help out, just let me know and we'll continue these sweet builds!

He wasn't understanding me I guess. He want reliability and didn't even now how to tune it.

He had limited knowledge of the 6.5 and the electronics portion. I figured best would be mechanical injection. The 6.5 is a different animal most tuning software will not mess with it. Tuners that know what they are doing are hard to find.

Could I see how you got your oil cooler lines are ran from the engine? Just put a 6.2 diesel in my 72 c30 4speed winch truck.

I have not posted anything in a while it seems. Truck has tons of miles on it with 0 issues tell now. One oil cooler line is leaking. I decided to remove the oil cooler and install a new aluminum radiator with oil cooler in it. The radiator has electric fans and shroud. The oil stays cool so being able to bring up to temp will be a plus. The engine runs super cool and egt's are never near max. Still have not installed the 4l80 yet. Truck cruises just fine and runs awesome. I did have the FFM blow apart at the bottom. I deleted the FFM and ran a better pre filter. I also redid the Fuel line into the IP.

The 4L80E does take a bit of power to drive but on the 6.5L's it's also a slug due to heavy torque manage settings in the PCM. Slap a 2200 stall converter in and remove the torque manage with an Intercooled Holset, and you are pushing the limit on the torque rating of a stock 80E.

If the tune you build blows this trans then good! I have a fully build 4l80 full manual I want to swap in. I was originally going 4l80 with manual valve body but could not locate one. I now have tons of them.
