I gotta start by saying sorry Matt. I hope this doesn't flood your inbox with requests now that it's clear, but i just gotta take a min and tell everyone how incredible my new hybrid race file is. I've been running ultra comp files for a while now but this tune blows away the ultra comp file, so thanks again.
And for those who have to wait for a tune be patient it's well worth the wait when you do get one from SPARTAN.
I've been sending more and more of these files out. It is a really hard file to outdo- they are actually dynoing more torque than the UltraComps, and within 5-10 peak horsepower too. What is truly great about it is the ridiculously low cylinder pressures. For a 425RWHP calibration, the peak firing pressures are just barely above that of our General Economy tunes, and actually are LOWER than the older Ultra Economy series. The low injection timing makes it less laggy, too.
On 04Excurision's severely damaged head gaskets, he couldn't run the old UE tunes due to puking issues. Hes actually running the Hybrid and it dropped the puking to a minimal
With pressures at a reasonable level, it can still be towed with so long as you have gauges. I haven't really put a tow limit or rating on it, but with a bit of common sense and right foot control any file can be used for towing and this one just happens to work pretty well. The EGT's can get hot if you pound on it; but that is where the common sense comes into play
