I've been reading quite a bit about the N75 valve. I found one posting that listed the part number as 034 906 283 H. I was searching for sites selling the valve and I found fastaddiction.com. However, they list both a H and a J valve? Does anyone know what the difference is? Also, I found a couple on EBAY that people were selling stating the valve didn't work with their programming. Is there anywhere I can find if it will be compatible with my TAP1 chip. I know I hear it is not the best chip out there, but not sure I want to spend more for a better chip. Thanks!

 

H.. i think the one people have limp mode/closed loop problems with is the J.
But you should really save for the better chip, you will have more hp and tq than with the race valve.. It would be worth it.

 

I actually think the J valve is the "race" valve... or whatever it is. But again, I could be wrong too... haha

As for the TAP1 chip, I have the same one... I've often wanted another chip, too... but it really isn't terribly worth it... our chip makes 50 hp and 50 lbs of torque... so it's not like it's a neuspeed or something! APR would give you the same hp, but with higher torque figures (closer to 80 ft/lbs gain) ... so you'd be paying for torque.

 

Oh i thought the tap chip was compareable to neuspeed. How much is the tap chip?
