Decided to try the quad 110, seehow much more power it makes over the hypertech. Question, seems a bit vauge in the archives, can you bump the rev limiter in sections, or just remove it? Two, with the speed limiter removed it just goes off engine limiter I assume..so whatever you canmuster at 3250 in top gear..I am guessing that is hardly above 100 mph anyways.

It bumps the speed limiter to 125 on 02 and newer and I thought I heard the rpms were bumped to 3400, dont hold me to it though.

That is correct. The v1.20 110 tune raises the RPM limit (on 2002-2004 trucks) to 3,400 RPM. The 135 tune raises it to 4,400 RPM.

holy crap...I am not sure I would have the cajones to run it to 4400, thanks a ton for the info guys, that 3400 I can do..same as the hypertech.
