I just found out, my trucks speed limiter kicks on at 92 mph...
Found out racing a V6 mustang...(don't worry I beat him anyway)
so do I need to get a chip to disable it?

 

Yeah a programmer will take care of that I believe....

 

get yourself an SCT XCalibrator 2 from Doug at Bama Chips ( www.bamachips.com )......it will get rid of the speed and rev limiter......and worth the money as far as power mods.....

 

cool, yeah I rarely like to go that fast, but I was wondering does that tuner get you better mileage as well?

 

yup....

 

Better mpg, more power, no limiters (rev or speed), etc etc.. best $400 you can spend on the truck

 

psst I disagree. But damn, I completely forgot about my tuner. I wonder if he will still let me return it.

 

well ur weird Tommy... everyone else loves theirs... i blame you

 

iv had mine for 3 yrs now.. still consider it to be the best power mod i have done

 

mines coming after the gears.

 

yea the speed limiter sucks screwed me a couple of times racing down th highway but it will hit 92 dam quick

 

Best mod I have even done hands down!!!

 

I'd be happy if my truck went to 100 because I don't want to handle it beyond there.

 

Love the "Bama Mod"!

 

MIght want to buy a radar detector too

 

if it had no rev limiter, the engine would go into the red zone, over-rev and blow. so there is no way it will get rid of the rev limiter. delay it a few hundred RPMs maybe, but in no way could it get rid of it.

 

yeah, taking it off would probably be a little too much, not worth it overall. what is the factory rev set at?

 

My 06 cuts fuel at 6200rpms and hits the speed limiter at 99mph.

These motors are short stroke. They'll take some rpms w/o a problem. I'd suggest not going more than 6500 though. Besides the most effective shift points are not that high anyway. There just isn't much point in reving a stock motor that high.

I have gone up to 103 with my XCal. and no more revlimiter I realy like it!

 

There is one use... scaring away rice.

 

I don't have any red zone on my rpm's

 

I have mine set at 6000, bama changed it to 6500 but I sort of felt like it lost power after 6 maybe Im dumb to think so!

 

I found that out too, that my truck bottoms out at 92 or so, trying to get to an accident scene w/FD.

How much did it improve your MPG, having the chip?

 

4wd trucks aren't meant to be driven that fast. There are a LOT of moving parts underneath your truck and particularly with the 4.10 axle ratios you've got, they're likely spinning VERY fast. Fast enough that there's a good chance of something breaking. The speed limiter is there for a reason: to keep your *** on the road with the drivetrain intact. There's no sense in messing with it.

 

i think it does lose power after a certin RPM but im not sure
