"We usually don't post a lot about what we break but since all the 6.7 carnage threads have been started I figure we should show the engine we popped back in early December which has already been replaced, built, and running through more tests.

This is partly the reason for our compound kit hold up because this engine let go with only the H&S can tune and our compound. Also we are not going to release these kits without a specific tune for them. Hp and torque numbers were much higher than our competitors even on the can tuning. Our kit is extremely efficient and we saw huge gains. We have injectors for the 6.7 also but will not put them in any of our trucks with stock rods. We do not release any of our products until they are completely ironed out (WE DO NOT LET OUR CUSTOMERS BE THE TEST BEDS ETC.) It's how we work. Tuning can band aid these rod problems, but its still a shear torque issue causing the problem. It has to do with how quick these engines can spool and make an extremely high torque number with the compounds and stock turbo at a low rpm. We have already developed remedies for all these issues and are already testing. including turbo changes ect. All we can say is there's going to be a flood of SPE 6.7 parts on the market this year... So please be patient with us. We are a customer based company who will only release a product that is damn near perfect...

As far as 6.7 performance goes, this is the only engine we are developing on.
