With just the tune you wont feel much. But once you put the headers in, you'll feel a big difference!

gzim335

so by you won't feel much u mean theres no gain or small gain?5whp? 10whp?over p31

His car does not sound like it has any exhaust work done. I gained 100 whp with my longtubes and OE tune and I'm non-p31. I based line stock 380 on 93 pump with ROW's and mikes power pipe (straight pipe). The car is a beast with this set-up.

gzim335

not sure how u can tell if he does or not with window open going wot the wind noise overpowers every noise recorded with my cellphone.
he does have primary n sec cat delete with stock resonator n muffler in place.
@mthis can confirm

w204nyc

Yea I'd say between 5whp-15whp

mthis

even after lth it wont make a dramatic different. u only gains solid 30-35rw with lth .

mthis

his got tune and stock exhaust decatted and filters. ither wise its got 190k miles or more .

I put an EC V4 tune on my 2010 C63 P31 and did not really feel much either but the throttle response was much better and the shifts felt much faster. I did a few before /after runs on my G-Tech in October 2013 at 10*C so the traction was very limited and I was not able to launch without spinning and having to lift and reapply throttle. I was no where close to good times but the runs did tell of an improvement over stock. My best of 4 runs stock was 12.924 @ 115.4mph and tuned my best of three runs was 12.742 @ 119.24mph. This indicates an improvement of .182 sec and 3.79mph with the EC V4 tune.

Maybe someone knows what hp increase this indicates on my car but I was happy with the results.

Almost 4mph increase in trap speed is huge from already p31 factory tune thats awesome

[I]To clear some misunderstandings this car is OE TUNED AND PRIMARY AND SECONDARY CATS DELETED, I owned since brand new 09 OP car is running very healthy but I thought that I would edge him out since I'm catless, but did not happen, I had a CEL light on OP knew it and these are the CODES I got I believe if I did not have CEL on would be a dif story MAYBE, im not to good in specs of these cars but I can drive them good if someone have tune only run OP he is cool guy and would meet up anywhere in try state area, hope someone can come up and do few pulls with his car this way he gets better pic.

Exhibit13

I agree with what others have said on my p31 I don't really see a difference with the EC v5 tune over stock other than the more sensitive throttle. Would love to do headers but probably never will due to smog checks and my warranty.

mthis

Sup G. your cars a beast bro for the miles it has and abuse its got i cant believe it still runs how it does

avery.whss

Anyone can say they have any mod

His exhaust is stock


that's what 2nd cat delete sounds like

w204nyc

Avery you're gonna lose this one. Check out Gonis account. He was one of the first to remove the primary cats. We are all from NY and we know each other. That video you posted is not sec cat delete. That has agency power exhaust. Check out his videos before that and you will see.

avery.whss

no im not, because something isn't right with his C63, I have the exact same mods..minus i have a custom exhaust and a custom OEtune but i've walked 2 stage 2 M3's and a tuned stroker GTR and a few corvettes, yet this guy can't walk a stock C63? Lol...wat? I highly doubt a "p31" has more power then my friends r32 gtr 508vboxed verified whp

mthis

thats my friends car. it has full exhaust. MBH headers and agency exhaust .

did u ever vbox u car 60-130?

mthis

C63c p31 should make somehwere 420-430rw stock
c63 preFL with tune and gutted cats (piping and cats still in place just inside cones gone) should make maybe 10rw more but dont forget the MCT is better over the 7G so thats why this was pretty evenm

no license, it's been suspended since october until probably october or november ..don't ask, BC's driving system is a joke, basically lost it for a year because i didn't have this stupid "N" sticker displayed properly

w204nyc

If it makes you feel any better I can run him. Mine is OE tuned with no sec cats or resonator. My car runs fine!

gzim335

R u coming saturday to mpact?

BLKROKT

You're the guy who thinks he has 600whp NA. Why don't you step out of debates where you don't have a clue.

gzim335

Do u have any videos of any of these kills?

w204nyc

I'm gonna try my best to make it, dont know for sure yet

gzim335

Pm me ur number if u do come well fet tog for few runs,i got my eurocharged tune files back so i can flash back to stock for comparison,what year is ur car?
