forge dv issue

[k1-dave]

i fitted a forge dv to my k1 and it came with 2 springs,when i went up the road it had lost about 100hp the car was gutless and engine management came on,so i fitted the other spring and the power increased but still felt a little flat.the next day i bought and fitted the evoms induction kit only to find that now when i accelerate i can here turbo chatter before i shut off, has anyone else had a problem because atm im thinking that the dv is leaking on acceletation hence loss of power,only other mods are a amd remap and help would be apreciated

mine only came with 1 , its green.

 

[k1-dave]

o right i had the green one on and it was weaker,i put the yellow one on and power came up but its still not strong enuff

 

[robdf2]

i rekon you have a boost leak somewhere mate.

 

[k1-dave]

thats what im thinking but it must be leaking in the dumpvalve as u can here it dumping air into the induction pipe when u accelerate,its very anoying,brand new car spent 4k on it and it ent running write

Put the o/e one back on to see if everything is back to normal.

Have you checked for any fault codes?

 

[k1-dave]

hmmmmm tried that but when i looked in the forge box to get the oem out the plunger seal things gone missing my mrs helped me clear up now i cant find it anywhere grrrr

 

[k1-dave]

how do i check for fault codes? do i need a machine to plug in?

 

[mhill]

Yep, dealer can do it or you will need Vag Com. Have a look in the dedicated and see if there is anyone local to you able to help.

 

[k1-dave]

ok will do cheers,does anyone no if u can buy the standard dv orange valve thing ?

 

[robdf2]

i doubt it mate , it will be a whole assy.
how did you come to the fact that you lost about 100 bhp? or you just saying its slugish?

if i were you i would check your conections again perhaps use soapy water to see if you have a leak some where?.

 

[k1-dave]

well with the yellow spring it probably makes about 0.5 bar boost as when it gets to 2700rpm u here it dumping the pressure,im just gona go check through the lot again and hopefully find the problem

 

[robdf2]

well i would say if your car was running fine on the standard valve and you have had problems since changing to the forge version then it shouldnt take you too long to find the problem.
did the yellow spring come with it? or did you buy it seperatly?.

 

[k1-dave]

both springs came with it,its doing my head in now,if the solonoid was faulty would the valve open easy or would it stay shut and not recirc?
