Have owned my Polar White 14 C63 (non P31) sedan since December 2015 and have only done cosmetic mods (front lip, trunk lip, diffuser, etc). The car already had secondary cat delete done when I got it, but that's it for performance mods. Finally decided it's time to step it up a bit, so I ordered my first round of mods:

Eurocharged V5 Tune + Handheld
AFE Pro-Dry S Filters
ROW Airboxes

Can't wait to get it all in and installed! Will try to do an before/after dyno as well to show the gains from these 3 mods.

Nice! The tune completely wakes the car up. Do you have an LSD too?

vipertoad

No LSD

I did upgrade the rears to 265's though.

Eurocharged V5 is gonna completely change the car.
You will gain a good amount and torque and a solid amount (70whp) on the top end if you're Non-P31.

vipertoad

Yes I've done tons of research on all the different tunes and chose Eurocharged because of their amazing reviews and customer testimonials. Their service is impeccable as well, as I ordered at 12pm and had a tracking number 2 hours later.

My car is a Non-P31, just a base C63 Sedan so I am hoping to have some great gains with the tune/row/filters.

Nice!! Car is going to be a beast. The downshifts are insane!

Highly recommend getting the LSD too btw. Mine came with LSD stock but recently rode in a friends' w/o it and it makes a huge difference in traction during hard launches and even "moderate" acceleration out of stop lights and such.

Mazspeed

The downshifts are the same as before a V5 tune.


Yes an LSD is HIGHLY recommended.

BLKROKT

But... but.... but..... you don't understand maaaan, the shifts are SO much way fasterer! I can HEARZ it with my ears! Bang bang crackle pop means more power and more faster shifts!

Mazspeed

Laughs.

chrisridebike8

70 whp is a bit optomistic. I made 380 whp baseline and 425 whp with tune only. 40-50 whp is what you should expect. I need to redyno now that I have headers. I expect probably 460-470 whp. No way you will make 450 whp from just a tune.

BLKROKT

Unless you're Avery ^

chrisridebike8

he pulls on stage 3 cars with a tune and cat delete.

MTV10

The downshifts sound more aggressive with the V5.
It's definitely not the same.

BLKROKT

"Sound" is the key word. Shifts are not any different in terms of speed.

Mazspeed

Sound relates to the different tune of the engine. Eurocharge doesn't have a tune for the tranny.
So the shifts are not any different at all.

MTV10

Yes I know that gentlemen.
TCU is untouched. Sound just becomes savage

Congrats vipertoad. I wouldn't worry to much about the before/after, just enjoy it .

Where did you end up grabbing the ROW boxes and filters from? I am in the market for those as well. Thanks.

vipertoad

Row boxes from parts.com..came out to like 305 shipped.

AFE filters are same everywhere (167 shipped).

Sante5000

I found the boxes on the site as well but don't know if they're the row boxes or the US spec.
help please

Amg63-

Curious to see the total gains.

Granted that the tune alone should only be good for 45-50whp (on 91 octane) but in combination with row boxes I would say it should be good for 55-60whp since the rows are good for an extra 10.

Also the tune should take more advantage than stock to make more power using higher octane 93/94 fuel. That should be good for another 5-10whp.

So with everything combined v5+rows+filters+93/94 octane I would say 60-65whp tops is very possible to gain over stock.

chrisridebike8

I got 45 whp gain with v5 tune and aFe filters on 93 octane. 65 whp...unlikely.

Amg63-

Adding row boxes should increase it another 10 to 55

Looks like I'm off by only 10 if at all

chrisridebike8

My mistake. I missed the ROW airbox part.

vipertoad

Honestly, if I gain anywhere above 40whp with everything I'd be super stoked! The car is already a beast bone stock with just secondary cat delete, can't imagine another 40+ wheel!
