Upgrades; suggestions and comments please
Hey there guys.

I've lurked this place since I got my 07 5.7 about 2 months ago, I'm ready to start modding mine but before I do I would love some input on a few different things. :)

So i haven't done much only swapped stock radio to a Pioneer AVH-X5500BHS, done tint and got some rims. Now I want some performance.

I'm stuck between 2 different exhausts. Borla 140158 or Gibson 617403 :confused:

Next, I want a BWoody 4" CAI. Does anyone have this or have any other suggestions?

Now I've noticed alot are opposed to lowering the 5.7 but its my ride :slapfight: :p Anyways, all I've found is Eibach Pro-Kit Lowering Kit. Is there anything else I would need to do or is this just a swap and good to go install?

Last but not least a tuner. I really need some feedback on this one. What do y'all use? I'm not sure where to even begin with that.

There will be more to come eventually but for now that's where I'm at. Any help/comments/suggestions are greatly appreciated. :thumbsup:

I am keeping an eye on this one as I am thinking about the Borla I am looking into the Volant CAI I ordered my catch can waiting for that to come in. I am looking at the pro kit as well. Also do you know Eibach is running a rebate thru July August on these. Just there site if you didn't. Well whatever way you go and keep us informed on how it turns out. I will be checking this thread

Before you spend any $$$ on other mods., I would highly recommend you clean the backside of the throttle body and add a catch can. There are many different types/prices, so you can do a little research and see which one sounds good to you. Many of us use the Billet Technologies unit (~$100). This is what I have on each of my Hemi vehicles.

As far as the exhaust goes, it's your choice. It should be 3 in. and have a resonator of some sort, or you'll likely get some droning when the MDS is active. The weak point in the exhaust is the "log" type exhaust manifolds, not so much the rest of the system. Consider getting some stock SRT manifolds/headers or, if $$$ is a factor, switch from the stock logs to the LX logs. Here's a thread I did on the difference:

As far as the CAI goes, IMO, save your money. The stock airbox flows more air than the engine is capable of processing. You can improve it by ditching the stock silencers, remove the drain cup at the bottom of the airbox and add a tube leading to somewhere behind the grill (see attached photo), install an AirAid Jr. or SRT tube from the airbox to the throttle body and, finally, add a good high performance air filter element.

A little info. on lowering your WK.....I've lowered mine with Eibach SRT lowering springs and SRT sway bars. I've also switched to Bilstein struts and shocks. I handles like it's on rails now. I've also installed an SRT front bumper. With this setup, the only downside I can see is that with the SRT front bumper, you need to be careful going up driveways and over bumps. I've had this setup for about 2 years and have scraped a few times and bent a support bracket once on a cement parking stop. If you keep the stock front bumper, you shouldn't have a problem, and will love the suspension. One other thing, the ride is more firm too.

Regarding the tuner, I have both a Superchips and Diablosport Predator. Again, it's your choice, and depends on what you're after. Both have their advantages, and would be outstanding if the good features of both were combined into one. The Diablosport allows you to update your PCM/TCM CALID flash files, and gives you more flexibility (adjustable) with regard to WOT fuel mixture and timing. It will also allow you to have custom ChipMaster Revolution (CMR) tunes set up for your particular vehicle. I have found that it also delivers slightly better fuel economy and performance. IMO, the best feature of the Superchips, by far, is the add-on (~$40) Advanced Transmission Tuning (ATT) Application. It allows you to have complete control over all up/down shift schedules, as well as torque management for both light and wide open throttle. You can completely tune out almost all the lousy features of the stock transmission. Throttle response with the SC is also better. For these reasons, I use the Superchips more than the Diablosport. You wouldn't know it is the same transmission. The DS only gives you limited control (up/down shifts for 1, 2, and 3), but does not give you any control over torque management.

Also note that Eibachs will need new shocks designed to work with lowering springs, as the stockers will wear out quickly from the higher spring rates. Bilstien's wil work, Koni FSD's will work also, but only if lowering 20mm or less. Replace all the spring isolators as well when installing the springs/shocks.
