Craig, thanks for the response.
Have you noticed any MPG increase? None
What makes it (for you) the best bang for the buck? $200 for 20 real hp
works for me
Also, do either the Stage I or II __require__ the use of premium fuel? They
both advance timing, the stage II more than the Stage I, Jet recommends
premium and because of the risk of detonation I would stick with it.
Sometimes you can get mild pinging that is inaudible yet long term could
damage engine.
And lastly, does the Stage I seem to fit what mods I have (or am getting) or
would it be a better
choice to go with the Stage II? They both will work however you may notice a
bit more advance with the Stage II however with the Stage I you may get by
on 89 octane. It's up to you.
thanks!

Subject: DML: Re: Jet Stage I for 4.7
I have had my Jet Stage II for over a year and still say it offers the
most bang for the buck. The stock PCM does not compensate for it...all I
suggest is that you always run premium fuel. Here is my summary of the
most common mods for the 4.7, I am sure many will argue (especially the
product
manufacturers) but here goes anyway:
Jet Chip II is worth maybe 10-25 hp and even a bit more torque Mopar
Performace PCM is good for the same 10-25hp if you can get one or
arrange for a custom flash Z Tube, good for a bit of noise and maybe a
few hp on top end Cat back exhaust adds lots of noise but makes 0 hp and
may even take some away Ported TB or 68mm TB is good for maybe 5 or so
hp Headers are again good for nothing but noise and maybe a loss of hp
IAT, I haven't tried, but it works on same principle as Jet Chip to
trick PCM to advance timing so I assume it works but not sure to what
extent Superchargers work but the ones offered seem to be problematic
and they void the warranty HO Cam looks promising but have not tried it
I think any serious gains would involve tearing into the engine or
replacing it!!! Don't expect miracles because even a 25hp increase is
only about 10% additional and really is not much when pushing a 4000 -
5000 lb vehicle.
Regards,
Craig
