Im thinking of putting a greddy profec B boost controller in my Z. Here is my question, do i need to change the size of the injectors or modify the amount of fuel some how that goes into the enginge to match the extra amount of boost ?? ANY BODY OUT THERE with just a boost controller and have no problems with knock or anything? Thanks in advance

 

As long as you have an aftermarket ECU and stay within reasonable boost levels, you should be safe.

 

AShspec and anywhere betwen 7 - 13 pounds. on a stock Z but with ECU intake and Exhaust 15 shuld be max

 

Ok Sweet. Thanks Guys

 

Bardabe,....the TT runs at 9 psi stock. It drops to 7 in safety mode. Stock injectors are limited. 15 is the absolute max on them.
