I got my A4 chipped two days ago with the AWE GIAC chip for the 98 1.8TQ and need some input on spring choice. I changed ut the green for the blue and it was spiking at 21 PSI but only holding 11~12 psi. So i tried the yellow spring and it would hit 14 and drop to 10 psi. this morning on the way to school i stopped by work, threw it up on the rack and tried the blue spring with a spacer. it holds at 12 but when trottle is applied it fluctutes widley between 16 and 12 psi.

Is it something i'm doing with the springs? is it the chip? might i have a boost leak. thanks.

 

might have a boost leak, and i think green or blue is supposed to hold the most but i dont remember for sure

 

I thought it was the red one when you go chipped? i want to know too

 

Here ya go, from strongest to weakest:

1. Red spring
2. Blue spring
3. Yellow spring
4. Green spring

If you are just chipped, the use the yellow spring. I think it's rated up to 23 PSI and the green one just falls a little short.
