Hello:  I'd like to know of experiences with a ECU power chip for the 2.1
Digifant vanagons.  I have heard about these, what is the lists experience
with them?

  Specifically what is gained, and lost by using them.

  What source(s) exist for the chips?  (and are all power chips the same???)

  On the same subject, what will a power chip add to a 2.1 liter with bigger
valves (ie Boston Engine stage III engine)?

  Any Californians experienced with power chips and passing smog tests?

  I'd like to get info, as my 2.1 liter has 168K miles, oil pressure is only
about 30 psi now on the freeway (Mobile One 15-50) and compression is less
than good (100 psi min, 135 psi max)  So I know it will be time for a
rebuild soon.  I am considering a replacement waterboxer, with some
performance upgrades like bigger valves and the chip.

  Also I have read of problems of mixture being too rich with the stock FI
and bigger valves (and I assume same for ratio rockers)  How does thepower
chip address this?

thanks, looking forward to some good replies.
