engine cutting out at 95 mph

[sudsy49]

does anybody know the solution to the 5.3 engine cutting out at 95mph

Get a hypertech and reprogram for a different speed rated tire, try to get a dealer to do it- not much chance

I belive the ECM has a speed limiter in it. The hypertec should be able to change that too.
But why do you need to go over 95???

[sudsy49]

didn't you ever get into a friendly race on the highway with a Ford or a Tundra or anything? You know, its a guy thing!

Is that going to be your explination to the State Trooper? Just kidding I know exactly what you are talking about, but $250 donated to the State of NC in 4 months has taken it out of me.

lol, noticed my 97 does that too. Supertuners will give you more power, but may not kill the governor. a power chip will though. If you are willing to spend the $$ to play, its not a bad investment. However, just to kill it, best bet is with a chip. Check with your local trick shop.

olt of the newer vehicles have a governor built into the computer now so the car or truck will not go over a certain speed. alot is due to the tire ratings. so manufactures have wrote a program into the chip in the computer to limit the speed of the car and/or truck.

Depending on the year model of your truck it may or may not be chipable. If it is 1999 or newer i would go with the Hypertech Power Programmer. It will add about 20 horsepower 40 ft/lbs of torgue, and that NIssan is going to have to run 128 mph to outrun you

I got a 1998 5.0 305 with airaid intake and a flowmaster my truck hits 101 then bammmm it cuts fuel it slowes but i can get it up quick. I took the honycomb off my mass sensor and my little niddle bottm of 100mph try that then turn on cruise control ones you hit 100 or 101 set control. hey i dont have the money to be buing chips programers. I even got 20'' rims on my truck

I had the same problem with mine until i realized that HAY THIS TRUCK HAS 126,000 miles on it and runs like new you know how they do that. they limit that RPM not the speed my 350 is limited to 4,500 RPM ya ya ya a small block should be good for 6,000 RPM yep and only 100,000 miles at best I finally decided that 95 is ok on the highway just like the automatic shifting itself even when you have it in 1st gear ....IT SAVES THE TRUCK AND GiVES YOU THOSE 250,000 miles on them

reading this makes me glad i have a 91,m 350 "with some work done to it", yep i got caughtr too, first time i really wound it out and busted me for doing 138 on a deserted highway at 3am just outside of palm springs, yea well ya play ya pay, at least he didn't hit me up too hard, first ticket in 20 years too.
