Found my old n75 put it back on and it boosts fine now so its either a faulty ecs valve or it doesnt like the revo stage 2 map but alex from tts is going to swap it so lets see how the new one works
 
my n75j gave up on me over xmas so I've been using my old C varient for the last week or so and its feels really flat.

Anyway I've order a n75h today for £35 from vagparts. I was guna stick to the J but thought I'd try one of these as its nearly £15 cheaper!

Why are people wanting to spend £60 on this so called "race" valve when most people say its the same as the H...??

Because it might not be a normal H valve and if you go into limp mode or have problems with the race valve I would imagine TTS will probably refund you. I very much doubt vagparts would.
 
I'm happy to take a chance with it working, if not I can probably make some profit on ebay!

It would be nice to know for sure if these valve's are different wouldn't it because the ECS one seems overpriced.
 
lol we're talking about this brown part (this one is a J)

Ah now it becomes clear. So.. the difference between all the types is?

Which is worse, H or J and what causes either to be worse than the other?

I'm still trying to grasp why this would be beneficial
 
Think Im gona go for the N75J next month as I've herd of people having isues with boost spicking with the N75race valve
