Hey guys,
Some relevant mods on the car:
Garrett GT3076R internally gated .82
3 inch exhaust with Cat
Blitz Single solenoid ebc
I had my car tuned a few months ago and the tuner couldnt get it to hold above 17 psi without spiking. Im wondering is this because of the single solenoid of my boost controller? Ive been told removing the cat will help in the boost spiking, and if this is true i will probably try that first. If not i will buy the spec r so i can run over 20psi as planned in the first place. What are your thoughts?
Cheers
