Ok, I just installed the ****** whistler on my 6.7 and you can really hear the turbo sing.. the problem I am having is that the check engine light is on and the truck seems to have a little lag in the low end now. dose anyone have any suggestions ???

 

u were getting it to sing... but did you also get the silencer ring out?? just curious cause cant tell with no sig. line info on ur truck...

 

It sings, quite a bit more than stock, the scilencer ring is still in. At idle and cruising speeds it is still pretty quiet but when you have your foot in it it sings a tune.

 

Can somebody tell me what a ****** Whistler is.

its a homemade intake, works nicely to from what i read. i just gutted my intake tube.

 

Did anybody get the whistler to work without throwing a code on the 6.7?

 

Check the MAF sensor and the AIT sensor, maybe they came unplugged.

 

i made one myself but i i had some surging and couldn't build as much boost....I double checked all my connections..I think i will have to wait till i have a programmer.

 

I like my AFE, it sings at idle after runnin her for a little!!!!!!! freakin sweet

 

That's all I want out of an intake... just a little (or a lot) more turbo noise. My '95 was loud and I loved it. We gotta make these things sound like diesels somehow, right?

 

Has any one figured this out what proworks1 commented I just installed the ***** whistler on my 10 6.7 cummins and my engine light came on and I'm getting really bad turbo lag almost like it not building boost right off the line if I give it a little more throttle it will take off spinning tires it seems to run fine at higher speeds it's just the take off at a light. Is it possible the whistler builds too much CFM? Any help please.
