Default Correct FPR pressure........Read inside >>>>>>>

ok my smart peeps.

Some of you know that I've been running rich (poor in the pockets, rich on the car ). I went to tyrolsport, and got an adjustable fpr. Now this is my setup:

Audi A4 1.8t '98.5; GIAC chip; 310cc injectors.

the chip is not tuned for 310cc injectors. Now, what should be the correct pressure on the FPR for this setup? or how would I know when I have the perfect mixture?

Default Try 28 psi of pressure at idle....

But, you really need to run the correct hardware/software combo, or you can't expect it to run that well.

Default You need to make sure you have the right GIAC program is you change the injectors.

Call Matrix Engineering 503-443-1141 to find out the proper FPR setting and to make sure you have the right program. From my understanding the stock injectors with a 5 bar FPR runs stronger then the 310cc injectors with the 3 bar.
