A question for Mr. Troyer
Last week I ordered the custom tune and airaid intake from you. Months ago I ordered the 1714 and underdrive pulleys from you as well. I have 2 questions:
1.) Last night I upgraded to the red top Optima battery due to my Winch CCA requirements. Will that also help with the dim lights at idle due to the underdrive pulleys or will you be raising my idle RPMS?
2.) How significantly will I potentially suffer from getting the intake and not the exhaust? I was thinking about cutting out the enormous factory muffler and replacing just that with a magnaflow or something, but keeping the rest of the original pipes.
Thank you in advance for your response.
P.S.- Your wife and others on your staff are a joy to work with. I have not had the opportunity to talk directly to you yet.

Hi Chemgod,
My last response got really screwed up with (apparently) the message server problems on this site - some of it got repeated several times, and some of it got deleted, etc. I had that problem with several of my posts last night - so I'm going to try to get you something that more closely resembles the original response I actually uploaded, so hopefully it will make more sense.................
First - as long as you have noted the use of underdrive pulleys on your CPW's (our Custom Program Worksheets), then yes, we'll automatically bump up the idle speed, no problem. And yes, installing the Optima battery was a smart move, you bet!
Second - Doing the intake but not the exhaust won't hurt anything or negate the power gains form the intake - what will happen is you just won't get quite all the power gain you would with the exhaust done too, with certain types of mods, that's all. Many people have to do their mods one at a time, and it's very common for people to do the intake before the exhaust, and vice-versa - that's OK.
In general, we prefer not to do just a muffler replacement as that is primarily a sound-changer rather than getting you the kinds of power gains you get from a proper cat-back exhaust. Figure 4-5 HP gain from a good muffler-only change, more than double that from a proper cat-back exhaust that increases pipe diameter - like I said in my original response, it is important to use a cat-back system that also has real flow engineering to bring back up the velocity of the spent exhaust gases, which drop when increasing pipe diameter - which is why we use Magnaflow.
You have done a lot of nice mods on your truck, it's obvious that you have taken the time & spent the money to do things *right* - so especially for someone like you, I'd say to do the complete cat-back system.
If you want to do a muffler-only change for now, and then do the complete cat-bahe idle speed, no problem. And yes, installing the Optima battery was a smart move, you bet!

Thanks again for your business & your post, & I hope this info comes out making more sense than my last garbled post did!

Chemgod,
Sorry, but it appears the message server problems here are altering my posts - repeating things over and over, then cutting other tings out, etc., causing it to not make much sense - I have this same problem in some other threads, too - I have put up a total of 5 different posts including edits in response to your questions, and not ONE of them was correctly reproduced here once I pressed the SUBMIT button. Sorry for the inconvenience, I hope you were able to get enough info from it to make sense, & please feel free to call us to go over any of this in more detail.
