So the stage two power pack install is complete (excluding the refitting of the plastic engine cover).
Runs really nicely. You can feel that she breathes better and has more power. Also a seems a bit louder as well given mine is running a 3 inch Borla s-type cat back.
Things that caused me some grief:
1. Sound Tube delete. Buggered if I can work this out. I have watched every U Tube video I can find on it and none seems to show you quite how to do it. My solution? Cut if off half way - lets face it, it does SFA in any case - and put some fire resistant expanding foam into the empty pipe then cap it. Not ideal I agree, and one day will probably sort it out properly. But the best I could come up with on a Saturday morning.
2. Little clips holding vacuum hoses onto the existing air intake pipe that connects the air box to the throttle body. The little clips are horse shoe shaped things a bit like a cir-clip. hard to get at with fingers my size. So I used a trim pick to lever them back and managed to break both clips. don't worry, you don't need them to complete the job anyway.
3. New air box. Take new air filter off BEFORE installation of the box. It allows you to put your hand inside and guide the rubber 'seal' to the correct 'fit'. Inverted commas used as the seal does not seal anything, and the fit is more like a rough outline. But that appears to be the manufacturers intent.
4. Wiring to the new throttle body - reuses the wiring from the old one. Pro tip - reconnect wiring to new throttle body before bolting new throttle body in place. Royal pain in the arse to reconnect afterwards.
5. Lower left hand bolt on the throttle body. For some reason the radiator overflow reservoir is in the way of the wrench. I should have taken my time and removed the reservoir, but dumbass here soldiered on and essentially stripped two bolts (one on the way out on the original throttle body, one on the way in on the new throttle body).
6. Software install. It's a bit finnicky for the technologically challenged. Find a 12 year old assistant and you will be right as rain. Either that or actually read the instructions properly a few times. I didn't get the email from Ford Performance web site, so I guessed it was going to require the password I gave it for my account when opened. Lucky for me that's how it worked out.
Also, the new throttle body bolts are torqued to 7ft pounds plus 60 degrees. That's not a lot and whilst I have been told real mechanics never use torque wrenches, I am not mechanically minded and will probably never use the $80 tool again. But the $20 per bolt peace of mind is worth every cent imho.
