Boost issues on t2 swap
 
Hello all,

I just finished my s4 NA to t2 swap and im happy to say the car is up and running and pulls like a monster :). My issue is that i am hitting the 8.5 psi fuel cut. I know i could get a fuel cut defender, but im wondering if my wastegate just isnt efficent enough or if its not getting enough pressure (due to pills in the lines or whatnot) to open the flap all the way. The mods on the engine are complete removal of the emissions systems, and a 2.5in downpipe and mid pipe that connect to a racing beat y pipe. I am also running a warblo 255. Any input as to ways to lower my boost or fix the fuel cut without leaning out and blowing up would be helpful!

Since you went with 2.5" exhaust you need to port your wastegate, and please don't get a FCD, the D means more Destroyer than Defender

Will I need to pull the engine to do so?

You need to take the turbo and exhaust off, so no...unless you really WANT to

Would intake restriction be a feasible thing to do? would it work?
