[Herr-Kuhn]

The real reason you put the MAF in place of the AFM is to gain in transient response. The car just takes on a more crisp throttle response with the MAF sensor. The MAF response is an order of magnitude faster than the AFM...because there are no moving parts. The PSC1-009 should be about $350.00 and a proper MAF about $200.

If you go PSC1-009...make sure to tell Mark you want the ability to adjust the altitide compensation. I have the first unit with that ability...the originals way over compensated for altitude and the car would simply not run at above 4500 ft...too rich. I was supposed to install that thing a long time ago, but have not done it yet. Mine has the ability to remove and replace resistors on the altitude compensation circuit. I have always said I don't think the unit needs any, or very little at best. Mark and I disagreed on this, but Mark agreed to let me test different compensation circuits on the altitude side...the unit has been sitting in my drawer for 18 months now.
