Highest HP tunes from Spartan or others?

[boostd6.4]

I have been away from the forum for a while.....

Who has the highest HP tune for the 6.4's now?

I am running the 310 Spartan as my DD tow tune, etc, etc., and I am wondering what has changed in the Market?!

I have never installed the 350 Spartan tune, as it required the TCM upgrade to be removed, and I just have not installed it yet. I may not even have the file anymore now that I think about it...... Wonder if this can be retrieved and sent from Spartan??

Thanks for any info!

My truck has killed the Suncoast with 22,000 miles on it, and 27,000 miles on the truck....

The 350 is the biggest tune I know of. Why do you want a bigger tune then the 310 if it already screwed up two tranny's?

The highest HP tune for the 6.4 is Eric's Xtreme Race tune. It has made over 600HP on fuel only.

BTW, I thought the Spartan TCM + SunCoast = BOOM?

Spartan is doing custom tunes now for the TCM and suncoast. They just say when you get your suncoast make sure its built with factory ford solenoids. TCM then takes the place of the solenoids and bumps the line pressure to where it should be.. if you combine suncoast solenoids with the TCM its raises the line pressure to high and is really hard on the pump...basically it can ruin your tranny.

I will have to check with Spartan to see if I have requested the provisions for the Suncoast transmission, or have them put in as the trans is apart.....

Thank all for the info! This may be why the input shaft was broken!

Was it your input shaft or your intermediate shaft? Usually it's the intermediate that breaks.
