Ramsey it looks like your VIAS isn't functioning properly. Every DE-K N/A dyno i've seen the HP was at or greater than the torque. Look into that and do the JB weld fix...

3rd gear torque is going to be higher but in 4th gear hp would be higher.

Hmmm...interesting. But look at the shape of the torque curve. It's looks to really be dropping off in the top-end.

When torque drops usually hp drops. When the torque curve stays flat it increases. I think it his just the gear he used since its not a 1.1 ratio.

I understand the relationship between TQ and HP. That's not my point. It's just the shape of the TQ curve that puzzles me. How exactly does dynoing in a non-1:1 gear affect the SHAPE of the curve?
