Stupid mechanical things you have done that cost you HP......
Ok before I started going to the track last year I decided to go ahead and put on an FRPP 65mm T/B and egr spacer. Well I got in a hurry at the time and wanted to bolt the thing on starting late at night so I could drive into work with it the next day and flog it. I get everything together to install the parts and I figured I would have it done in less than an hour. I start digging through the boxes and the FRPP kit comes with all the gaskets but they forgot the egr spacer to upper intake gasket. So I figure well I have to drive this thing so I will just reuse my original one which came off in one piece. I got it all put together and I also put on my 75mm Pro M(at the time) while I was at it. The car ran great I must say. I ran it this way all season at the track plus about 8k miles of commuting.
Well I had to go back into the upper intake area a while back and this time the egr spacer gasket was not reusable so I got a new one from ford.
ALL THE SUDDEN THE LIGHT BULB WENT OFF IN MY HEAD. I was using a 62mm(or whatever stock is) gasket the whole season which basically negated any gains of putting the t/b on in the first place.
The moral of the story is to pay attention to what you are doing even when in a hurry.
LOL I'm probably the only guy out there with a ported egr spacer gasket. :D
