    Headers, Do I need to tune?

    I agree, I'd get the tune first too. But I had my LT's before I had a tune. I did have a cel for the rear o2 sensors. But the nonfowlers did eliminate it. And my truck ran great.

    Headers, Do I need to tune?

    This is not true. You may get a code for the rear o2's but there are tricks to eliminate them. Stacked non-foulers being the most common. I ran my LT's without cats using the non-fowlers and the code would come and go. But the truck ran great. I wouldn't even consider shorties.

    Performance help!!

    I dont think they make the one you need anymore. Look in the classifieds here and other forums. Im using Diablo but my truck needs custom tuning to run. Look up Redtruck-VA or Tomater03 they both have an 03 and can tell you which superchips to get..

    Performance help!!

    Superchips and Diablosport are both programmers. The Diablo allows for custom tuning if you plan to go crazy. The superchips does not allow for custom tuning. But the Superchips has better canned tunes and also has a trans tuning option for the 03 where Diabl does not.

    Round Rock Tx just north of Austin. Born and Raised in Austin. It sure isn't what it used to be. To many Liberals from Cali moving here.

    Performance help!!

    For the 03 if your not planning a whole mess of performance mods the early model Superchips will be your best option. I dont recall the model number off hand though.

    Uh Oh. Guess it'll be over at Aikman again. I'm surprised he wants the trans. I though he had a built trans?

    How do I remove the air cleaner assembly? 95 Ram

    You may get a better response if you post this in the 2nd gen section.

    spark plug wires - question

    You will have a coil over the primary plug. The wires go to the (waste spark)plug on the opposite side. I'd recommend doing them 1 at a time as to not mix them up.

    Jay Greene vs Hemifever?

    You will be hard pressed to beat Moes pricing. And if you find one cheaper verify shipping. Shipping is free from Moes in the lower 48. You can buy the Diablo without HemiFever tuning. Its a drop down menu.

    Best Header Gasket and Header Bolts?

    The 6.1 bolts have anti-seize on them, not loc-tite. The Mopar 5.7 gaskets are highly recommended. The 6.1 has a different shaped port.

    Cheapest ported throttle body that will produce power ?

    If you can deal with the downtime, sending your stock TB to Fastman will be the cheapest route. The standard bore if you don't plan on opening the engine. True bore if you do. It is a supporting mod and you won't notice a big difference by itself. But i would do all the bolt ons before opening...

    I think you're more than a "little" biased...lol

    4.56 or 4.88 rear end gears???

    Moes Performance, Matt is a vendor/member here and a great guy to do business with. But be careful you may find yourself in more debt once on his website....lol

    4.56 or 4.88 rear end gears???

    Really depends on how much highway driving you do. 4.56 will be more than enough gear for 35's.

    Anyone running procharger?

    Its because of the transmission. Replacing trans after trans is a pretty big expense if you drive right once the SC is installed.

    16' ram running great

    Now he has a new baby. The 03 will become a memory. lol

    6.4 in a 3rd gen

    Stroking the 5.7 to 6.4 will be easier and net you better performance in the end.

    Tuner Settings

    I would say the performance 93 would be the best. Or a variable of that. I'm not familiar with super chips. When I was running the canned tunes in my Diablo I felt the best performance running the 91 tune with 93 octane gas.

    Coil spring swap?

    As I was typing my reply that crossed my mind. Lol
  24. ATXHEMI

    Coil spring swap?

    You would be better off using the 6.1 springs. the 2500 5.7 would be the same springs. Unless your not talking about valve springs.

    Heads

    I have my heads milled. 0 issues. I would imagine you will need custom tuning.
