Wondering if anyone has any info of adjusting a 1990 TBI 350 for altitude. I runs great at sea level, but has been a pig ever since I moved into the Mountains. I'm also looking for info on Adapters for the speedo. I run 33's right now, and my speedo is off by a bit. I'm told this is also the reason the ABS and cruise control don't work. HELP! Thanx for any help. Why do people keep calling it a Bronco!!!!!
