Most say theres not a need but that depends on what your doing , but everytime I visit the hundreds of forums it seems nowaday theres always the 4000 RPM ?? and he knows it , and when or if its out I'm sure he will let everyone know
4000 RPM tune is never going to happen. The ADR cant control the computer system like a programer can. That means that unless you have a stack with a programmer that can reach 4000 RPM's your truck will never hit 4000 with only the adrenaline. Sorry for the bad news.
Well Justin at Quad said its never going to happen. His reason was that the box could try and reach 4000rpms, but if the computer has not been told that it can go to 4000rpm's then it will reach somthing like 3500 then shut the engine down. Like I said before the only way to reach 4000 rpm's while running a quad adr you have to stack a programmer or somthing to reflash the ECM so it knows that 4000 is a safe zone. The quad ALONE will not get to 4000.
