GH informed us that they only provide the "8k tow" and "8k tow with fuel" tunes for econolines (the website doesn't say this
), so it's back to researching for tunes.
Found blessedperformance, innovative diesel and quicktricks...and leaning toward blessedperformance at the moment.
The atlas 80 did raise temps maybe 30-40 degrees?? for a freeway onramp that we use for testing WOT...may need to datalog with the x4 for each tune!?!
And for "what did you do to your smb today?"
Removed the gear oil from the D60 front and rear axles.
Added 1/8 npt magnetic drain plugs to each cover (one tough SOB) https://www.summitracing.com/parts/ssy-50-8334
Reinstalled the covers with LubeLocker gaskets https://www.lubelocker.com/collections/all
Will add the amsoil 75w-140 oil tonight.
Bought parts to replace the breather vents.
Replumbed the DIY coolant filter after testing the coolant...we found little black specs when collecting fluid from the radiator drain.
Changed the coolant tank because the original was coated with orangish sludge.
Replaced worm gear clamps with OEM spring clamps
