Standard TS Chip vs PHP???

[Grizzwold]

I just installed my TS chip from PHP and I noticed that my truck doesn't have nearly as much turbo noise as my buddies truck that has just a standard TS chip. My truck pretty much sounds the same as before I installed the chip, I was expecting to get more whistle from the turbo after the install. Any thoughts on the engine sound after a chip install? Thanks

what is your exhaust and AI setup?

[Grizzwold]

Straight exhaust, stock diameter, with K&N cold air intake. My buddy has the same set-up. His truck is an early 99 250, mine is a 2000 250.

alot of the difference could be that he has a wicked wheel in his turbo from the factory, and you don't.

[Grizzwold]

So the early 99 trucks came with a better turbo wheel?

[daboostcreep]

Yes. Along with more turbo spool sound, there is a slight reduction in surge that is experienced in later model 7.3L's.

Thanks for the info.

if u get a wicked wheel youll give up some compression over the turbo noise. Im not sure why one would want to do that...stick with the later wheel it works better.

I have a WW, DEFINITELY better response than the stock wheel, the factory ones arent as noisy but definitely worth it, especially when you get surge.

That's what I noticed on my buddies truck, he seems to have better response and a lot more whistle from the turbo. I wouldn't mind the extra noise if I could get that much more response out of my truck. His truck just seems to always be right there, where mine has some lag when you mash the go pedal.
