    Tell me you're not driving a 2013 International with a Maxxfarce motor.

    Yes it’s a 13L. Bought it with 177k and now it has 513k. It’s a solid truck. What’s wrong? Just trying to get a few extra ponies out it. The original owner spec’d it to 430/1550. I want to bump it to the top 13L spec of 475/1700

    Nothing wrong with that, makes driving better. Went from 5 to 6 on a 60 series, best money I ever spent on a truck, And if you have a
    Int, you will spend money. Dr in Effingham does good work

    I would have to check with the shop I got my ecm work done at, but I'm 90% sure I've got a Diesel Spec tune in my 6NZ and it flat is a runner.

    I drove a International company tractor that developed a nasty oil leak near the turbo. Spent eight days waiting for it to be repaired at SanTex in San Antonio.

    Had a healthy dislike for those trucks ever since.

    Yea I know a guy had that same issue. Lucky it hasn’t happened to me. I did have to replace the EGR coolers once and get the DPF cleaned tho. But the engine itself is solid.
