Maybe because addressing the Open Loop and Close Loop probelm with this kind of work?also, I vener said I would get an Apex, just wanted to know all I can about it and its problems.

 

you could more effectively tune with anything when you convert to a return line setup. I did it for my turbo xB, its well worth the trouble. The only thing is Perrin made a fuel rail with an open port at the end of the rail so I didnt hafta do all the welding your stuck to doing until someone makes a rail for this car

 

if u have a rock steady AFR , like others have with emanage . thats all u need to effectively add timing to max performance .

 

With this u don't have to play around with anything, u can do it with no hassle. One more thing down.
