C'mon Mike, please don't suggest these Hacks.

HemiFever and Flyin' Retard are likely to get their legs broke if any of the Truck Guys ever find out where they live for the amount of vehicles they locked up and had to go back to the dealer for re-programming ($$$$$$$$$$$$$$$$$).

The Daimler and forward era Hemis are uncrackable, this is common knowledge (but still ignored by people with their heads in their asses). Changing the shift points and fooling the ECU to think the engine is in "cold, closed loop" operation is not an "upgrade". This has all been debunked (google it) so move on with your lives. The Gen 3 Hemis are over 1 hp per cubic inch and still beating emissions: they are on the ragged edge of performance/compliance. Stepping over the compliance threshold means carburetion, expensive intake manifold, and expensive but unreliable ignition set up. It's been done, but the gains are hardly worth the expense.


Gotcha. Well it’s my everyday truck, not gonna go nuts.
So after hear that Grizz, I think I’ll leave well enough alone.
