so i recently installed an N75H race valve. I like it because in 2nd-5th it will spike to 9psi (stock tune) and hold 8, which is better than the stock N75. However, i cant seem to get anything higher than 5psi in 1st gear. Any ideas why this would be?

You're still on stock programming? That's why.

People are under the impression that the race N75 valve will do something for them... It's completely untrue and will only hurt your performance because your car was tuned for a specific valve, and it's not the one you just installed. When you get aftermarket tuning SOMETIMES they tune using the race valve, but still most times not. If you're looking for more power, get a tune, not a N75 valve. Or run an MBC in standalone if you want.

if you keep it, then get your car flashed/ chipped...

if not chip/ flash, go back to stock
