    I'm new to this site and modding cars as well. I drive a 2006 magnum srt8 and its my daily driver but I do intend on gettin on it every now and then.

    I was wondering if I should install a camshaft or a torque converter first? Sorry if this has been asked before.

    Also I've been reading a lot about these diablo tuner or predators or whatever. Can someone explain what they do and how they correspond to other mods?

    Thanks again for any positive feedback!

    I say do a stage 2 package the whole top end cam, heads, intake. The parts are cheap with the core exchanges the labor is the issue. It sucks paying for labor twice!

    OK. So there are options. Since you are a 2006, your rear end is not as rugged as the newer LX cars on Getrag rear ends. A higher stall torque converter could lead to rear end issues because the preload will be higher and your would be sending higher torque under launch. Bottom line, I would look at upgraded half shafts before the TC.

    On the CAM, you would get a performance boost plus a better rumble. I'm a big fan of the Hemi "tone" and improving the sound is awesome. We have a member with a nice cam in a SRT Jeep that sounds freaking awesome. Granted, it's a 426, but still the rumble is awesome. I would definately recommend it and as mentioned, it's relatively inexpensive, especially if you do the work yourself.

    On the tuners. Diablo is the most common choice for the Hemi. These are basically interfaces that allow you to modify the way the cars "computer" or ECU manages the engine throughout the RPM range. This is typically done through "canned" tunes or custom tuning. Canned tunes are those that are generic. They can be run on stock vehicles or those with certain bolt on mods. A custom tune is one where you have your specific car tuned to perform at its best. Typically this is done at a dyno and/or with data logging.

    Diablo has nice "canned" tunes that do boost power. It is a noticeable change on a dyno, but not really in the "seat of your pants" feel. It does, however, improve fuel mileage. Can't hurt. Now if you are making modifications to the top end (cam, intake maifold, cold air, etc) you will need to have the tune modified. The best is a custom tune for your specific car. Well worth it but expensive. Expect a custom tune, with dyno time, to run you between $300 and $500. It all depends on the talent of the tuner and supply demand. In South Florida, that would be the running rate. It can vary a great deal depending on where you are. You can also data log (basically record the car while at the drag strip or with "spirited" driving for a time) and email that to a tuner. They can use the data to creat a tune.

    Long answer... but I hop it helps...

    These are two items that go together like peanut butter and jelly...decide on a cam first, then size the converter to match. You want your stall to be close to the area in RPM you are making good to good + power upon launch. You want as much power there as your drive train and tires can hold and not break and you leave without any to little tire spin. THe bigger the cam the higher the stall. Larger duration low LSA cam make big power but in a tightened and up the curve manner. Big cam means big stall and leaving at 4k+. Weekend warriior get on it ever now and then, call Andy at PWR for a cam, install yourself, or have it done by a competent shop. Get a diablo tool...learn how to use it....not difficult, just figure it out. Contact Jhoan Mangs at [email protected] Guy is the real deal and very good at what he does. Get the tune dialed in with the tool, dyno it, then choose your cconverter from that data. I would recommend a FTI Econo XXXX stall (whatever stall that best fits your cam) Best bang for ya buck. Well built and affordable. I run one behind my 426. Make sure your add the 09 R/T half shafts and hubs, those are a weak area on the 06's.
