Thelma - 2018 GT Premium convert into a PP1

[2016S550]

ordered Roush intake restrictor for intake, EO carb sticker and the sound tube plug. Hopefully be here next week. This will let me install the intake with no tune. Then if i do a tune just remove the MAF intake tube. Still searching for a good deal on the muffler actuator motors.

Plus put a new battery in car - was on vacation for three weeks and battery died. The negative battery post actually separated from case. The outgas actually welded the negative battery terminal to the post. New battery and terminal fixed it.

then car popped a P0305 - cylinder 5 mis-fire. Bought NGK plugs as car is at 63k and will put those in this next week.

Did the plugs fix the PO305?

You know after clearing codes and drive. The P0305 didn't come back. I still need to put in the new plugs.

Decide to buy the Ford M-9603-M8B Ford performance kit. Got it for $850. Deciding factor was just to improve rhe transmission shifting and some power down low. Plus still thinking of swapping out the rear axle to 3.55. We drive the car on long road trips and want to keep the mpgs in the mid 20's
So selling my Roush intake for $300 - have not installed my switch-fire yet.

Install pics. Sound tube came off pretty easy once I removed front tire and fender liner. Was able to reach in with a pry bar and pry the sound tube tab off bolt.

Shift clean is very nice. Almost worth kit in itself. Some power down low. Little bit on top. Just drives better.
Only weird thing was how much quieter the cabin is without the sound tube.
Going to install borla switch fire next. See how much sound it generates.
