who has tuned their stock Crown Vic? J-mod?

Just aquired a stock, good running 04 CV Sport for driving to work and on trips.
Thinking about buying Marty's tune, of course it will be a good tune - I just wonder - does the Crown Vic really wake up at all?
leaving it otherwise stock. 87 octane.
3.27 gear, convertor, air box - stock!
I really enjoy better shifting mostly. I got a drilled j-mod seperator plate with the car - just install that?
Marauder has the mod money, just wondering if your Xcal tune in a CV made you smile and never look back, or were your bolt on's what made it better?
cash is tight, need some thoughts beside my own :shake:
thanks!
 
The trans tune will make the car a lot better.
Not much to be done power wise with 87 octane
 
^^Agreed. A combination of both a GOOD tune and basic bolt on's will make it a fun driver.
 
We have tuned a large number of CVs and GMs and the number keeps growing.

Folks seem to appreciate the cars a lot more with a tune in them.

the no power answer I sort of expected.
I was most pleased with the new shift schedule and raised top end limit when my Marauder was n/a.

A marauder trans file will go right into a CV pcm.

Marty, maybe you can overlay my awesome Marauder shift schedule when you do the CV tune, and it should be similar on the road?
> I'll contact you as we discussed.

thanks guys!
see the NO MORE MODS' guy still laughing at me in my sig?:shake:
next it will be an intake, then 3.55 posi - you watch.
It's an addiction and this forum is my dealer :eek:
 
You will definetly want the MZT mod

Marauder airbox (80mm MAF) the 04 airbox works too but requires a repin for a difference harness connector
"Ziptube" ideally from an 04 CVPI or ADTR's tube
Tune

The 80mm MAF and intake tube were worth 11hp factory ratings difference, combined with a tune it really wakes up the car and improves the noise considerably(you will be surprised)

Upping it to premium fuel will help the difference with the tune, but not completely needed.

Trans tune and/or a modest JMOD are helpful for increasing how sporty the car drives. I would put the separator plate on and leave springs as-is, and have shift points adjusted.

If you want to get into spending more money, 3.73's, metco's and addco's made my vic allot more enjoyable.

thanks!
I've read all this on crownvic.net long ago, trying to NOT get mod happy on this driver. And 87 octane is all I want it to need to keep cost of ownership down.
But shifting right is a good reason to tune.
 
MZT + the plate

I've got my marauder airbox that I have been thinking about parting ways with if you are interested.
 
How many miles on it and did you get a good deal on the lx?

Thanks for the complement on the g bodies in the other thread, down to 4 of them now.

Got any pics of the cv?

very cool, thanks!
I have the JLT cold air intake kit and stock MAF removed from my Marauder when the Eaton swap was done. Will these fit the CV?

123K, I think it was priced right. Looks like this:



 
Good looking ride!
I would j-mod for longer trans life and tune, k&n in stock box, and drive................
Got the Marauder to play!!!

Never seen the chrome tips like that, that I recall?
 
Nice!! Hope it was a good deal. Up here, everyone thinks that because it says "Sport" it's really rare and worth a ton of money, when it's really just a high millage, clapped out POS.
 
So what all good happens with the trans tune? What Can I expect from MO? Sorry to but in but it is related to your thread, just on my car! :)
 
The 4v has a different throttle body profile than the 2v and JLT tube will not fit, but the Marauder MAF and airbox are perfect, but will require a tune to use because of the larger MAF 70mm vs 80mm which is where most of the power comes from.

try searching junkyards for the intake tube from an 04 CVPI only, the 03- is identical to yours and the 05+ had a change in the PCV and IAT attaching tubes. Otherwise check out ADTR for his tube, a bit spendy but perfect for the setup.

yup, Marauder to play :)
Owner put the tips on when he did mufflers. I like them quite a bit - NOT Marauder tips like every other CV...

I agree. I figure, price equal to a CV, then add for the buckets and console.
This was NOT a P71, so she's still plenty tight and quiet to drive. A nice note from mufflers to 'feel' cooler than stock CV. Handling mods and fresh brakes we know Panthers react well to.

the trans shifting from a good tuner changes a Marauder to the car it SHOULD have been from the factory. It will shift at higher rpms, firmer/faster without lag between gears, lock up the convertor a bit later, even deceleration feels better because the downshifts come at a more correct speed/rpm.
With a CV , maybe not as extreme an improvement, as they are not quite as 'lazy' as Marauder shifting, but still seems from the replies that similar 'feel good' shifting will be had.

good info, thanks! I'm not going to start the cash dropping on it, unless after a week, I decide it really could use more..if my 'free' stuff fit, that would have been killer.
The improved shifting from a tune is my greatst reward, as I am part disabled and can't shift with my right hand. Automatic needs to be 'sporty'!

thanks for the input guys, I'll post up as I do change anything, and if it seems worthwhile.
I'm reading more guys here with CV in their collection, so it might help someone else decide on their car.
I can tell you straight away, I'll grab a used posi rear if I trip over one, that and a little more gear ALWAYS makes a street car feel quicker :D
