Come to mine eck and il do it for you ;D

On my way lol

Just been getting bored of the leon tbh its to quiet and refined and feel the need to do a bit of modding to it to lift ma spirits up with it.

Done the airbox mod today and its very worthwhile so gonna give the bypass thing a go.

So has anyone got any pics of how this is done???

i fancy this mod but since i run an mbc for boost control I'm concerned that i will have removed the only means available for the ECU to thorw my car into limp for basic protection.
i.e. 1. drop duty cycle to 5% via n75 valve.
2. vent excess boost to DV via n249 valve.

will i have any protection left or am i left on hoping ecu will reduce injection period etc.

took all mine off. under the inlet there is 2 nipples coming out of inlet..

1 to fpr and 1 to the n249.

i had new vac piping anyway so simply just through the lot away ran a pipe from inlet straight to dv.
there is a fault present but ive not got around to putting a resistor in the n249 wire.

i noticed straight away the dv response was alot quicker but other than that not much difference

no need to resistor to stop fault code, just leave the n249 plugged in. no fault on mine for months. if you have a fault its from something else then.

You do what I do, Carl, keep a close eye on the boost gauge

i have totally removed mine to get rid of all the crap under the cover.. so i need reisistor

Did this 2 day and what a difference it made on my car i did a few other things aswell swapped my DV round and put my boost gauge on FPR

 

[Witalik]

do you also have a before picture ?

i am noob so i dont know what is defferent on this picture compared to original ?

And so there is some winnings in doing this ?

that is standard pic ive got, the normal black pipe runs from N249 valve and under the inlet manifold
