need help ASAP

My TCS is only doing around 3.80-4.00 @full throttle. I adjusted it to 42-44. & my bl is 150. The car is an all original 87 Turbo T.
How do I tell if TPS is done. Also since my bl is so high is that because my stock fuel pressure regulator is done?

You need to get the TPS voltage to go above 4.00 volts at WOT. Check and make sure the floor mat isn't under your foot and if you are still having issues check out this adjustment guide. http://www.vortexbuicks-etc.com/tps_adjustment.html

With a BLM of 150 I would say you probably have a vacuum leak.

I wouldn't sweat the TPS setting. 4.0 volts and above is ok. As mentioned you may have interference from the carpet. You may be able to get a little more out of it by pulling the TPS sensor forward when you adjust it. As far as the high BLM's...could be vacuum leak, bad MAF, or bad O2 sensor. If the car still has the stock chip in it get rid of it and put a TT chip in it.
