Pocholin,
where and how did you have the speed limiter removed from your car. What other kinds of upgrades do you have.

I haven't had the speed limiter removed just yet, and I've only done K&N air filters and insulated the airbox.

How does one insulate the airbox? What materials, etc.?

I used thermotec insulating blanket, cut it to fit the bottom of the airbox and made it fit just on the edges of the box so it will be hold by the air filters and the box when you close it. I also wrapped the air inlt pipes and used some self made clamps that thermotec sales, all for about $80.00 it just takes time and patience. I bought the 10 sq ft blanket, it is a nylon with reflective backing
Here are some pics

OK, I'm no expert at this, but his is the best I could do, it works, it might not be pretty, but it works.
