Anyone towing with a tuned/modified Ecoboost?

Should do some reading on the Ecoboost specific forums. The moment these motors hit the lots tuner shops picked them up and have been playing with them since. The one that seems to be leading the charge in "reliable" tunes is 5-star tuning, same shop that tunes a lot of 5.4 and 6.8 V10's on this forum. Their 87,89,91 towing tunes are considered to be the safest with increases of 50hp and 50tq.

Now there are "performance" tuner's out there that are doing 50hp and 120tq on 93 octane, but word is these engines are pretty dang reliable. As for drive train through my reading it seems that the transmission / drive train can take the abuse it would be the block that would go first apparently.

I'll keep it stock myself have 90% of the 420tq at under 2k rpms is just insane, scoots this 6000lb truck around like no other truck I test drove. Curious to see what it is like with a load on it at highway speeds.

Something to remember is that a gain of 50hp and 50tq is going to happen at 5252 rpms ± not very much... The 50/120 tune is going to be a much lower rpm tune, it's all in where the tuner wants to make the power.

I do custom tuning on 03-07 Dodge Cummins engine, not 100% relative but I do know how to make a hp vs a tq tune, and just showing I not running my suck... A low hp to tq tune means low rpms, and is generally harder on drivetrain, nothing "bad" about that if the drivetrain is up to the task. Can the drivetrain take it??? Its a distinct possibility, I don't know one way or the other. I have ran tunes that increase torque by 100 ft/lbs and hp by 7 :-)

Just like when the Cummins went from 660 to 800 ft/lbs in 2011.5, but hp was unchanged. It's all about the rpm where you want the power.
