Car seems slower after KO3's fitment

[Spud_G40]

Hey guys, My mate fitted a KO3's to my MK3 today along with a forge TIP i bought. It just does'nt seem right, and I'm on here to ask why.

Engine spec of my car =

Jabbsport stage 1 generic map
Forge recirc DV
Jetex cat back
Dynatwist
N249 bypass

Fitted today = KO3's + Forge TIP

It just seems so laggy now (almost seems like there isn't a turbo until 4.5k or 5k), and has no pick up at all . Could this be down to it needing remapped to suit the KO3's? If so:- I am getting a blueflame d/p cat, and FMIC then getting a Jabba custom map after that anyway.

I had my mates MK4 cupra while he was fitting my K03's, and his has a milltek d/p + cat and a 4bar fpr with revo stage 2 and it just goes like stink, wheelspin/torque steer and it just takes off.

HELP! Thanks in adavnce.

as far as i know you definately need the exhasut and downpipe sorted and will need another map for the K03s. that's why it will be feeling sluggish. i'm sure others with more knowledge will be able to help better.

 

[David_smith_909]

like you said, get DP, and map

FMIC will help too

EDIT: too slow

run it in a lower boost state unless it's mapped for the greater airflow of the k03s... the potential to run lean is pretty great

 

[nick s]

that's why i'm resisitng fitting my K03s until i get the intercooler all on and booked in for mapping. can it damage the car?

 

[Cupra_Wayne]

Sure it is fitted properly?

Ran mine on standard map for 9months It was fine

 

[m0rk]

.... but running it on a 'tuned' map without suitable changes to the fuelling isn't a good idea - not the same as running std boost

yeah h17och mentioned to me that you did. so is it okay to run it on the standard map for a while because it's low boost?

 

[Spud_G40]

So it will be ok so long as I stay off boost as much as possible? How can I make it run less boost meanwhile without a remap?

 

[Martyn]

Did you reset the ECU? The N75 duty will be up the shoot until you do....

 

[Spud_G40]

How and why do I reset the ECU?

 

[Martyn]

Searchy searchy!

 

[Spud_G40]

Can you not just tell me the reason behind doing this?

 

[cupra_matt]

When i put my K03s on i was running a generic map ( revo stage 1 ) and it drove beautifully, how have you piped in waste gate actuator as K03 has 2 pipes and K03s has just one.

Should be running fine mate. Its more like a installation problem rather than software.

 

[Spud_G40]

Yes?

 

[ibizacupra]

Yes. Pics......

The pipe going alone to the actuator is ontop of the valve on the left of the picture.

Does this look right?

usually goes via solenoid unless you have deliberately bypassed it.

I suspect plumbing is wrong.

 

[Spud_G40]

Here is a picture to show where all the vacuum pipes are going from and to.
Is everyone elses the same? (the pic shows the actuator one going from red to black vac hose)

Any comments welcome.

Unsure off the top of my head, but if you bring it down one night we could compare to mine. (Even though it is a K03)

 

[Simon L]

Actually, looking at that pic... one of the pipes form the N75 is supposed to feed back into the TIP near the MAF... maybe it is piped up wrongly.

Do you have a boost gauage? what boost is it making?
