Y pipe done

[Jeff Powell]

Did the y pipe from Zabtech yesterday, went smooth and easy however now in park and neutral, the engine won't rev over 3ooo RPM it does down the road however. Not that I need to rev the engine that high at rest but was just wondering if that will poas a problem in the future?????

The engine never reved over 3000 rpm's in neutral or park, its a safety feature..

Jeff,



That is the rev limiter kicking in, it is completely normal for the truck to do that....

If you get a tune or chip it can go away.

Thanks gentleman, never noticed it couldn't do that before. I'm anxious to save some $ for the next part: coldair intake!!!!!!

Is the same 3000RPM Park/Neutral rev limiter on the 07 V8 ST? I'm not driving my truck today or I would check it out myself.......

If so that's very interesting and I was not aware of it.

My 01 will rev to any RPM in N or P. Came that way.

does the y-pipe really keep the exhaust heat away from the transmission? i recently had to replace the transmission on my 01', the heat from the exhaust fried the valves, and i am not looking to do that again.

Callan, by removing the Heat that the cats produces it helps keep it cooler, BUT the ST tranny is known for bad valves, I think the tranny shop was pulling your leg...
