[W126 Coupe] Performance Chips

[Jonathan Hodgman]

I have one reasonably close by, but I stick w/ Known items, ie headers, 
exhaust, cams, coatings etc..  Building a 5L M117 twin turbo (old Koenig 
kit) that's headed down to FL to be fitted in a Gen I Koenig widebody..:)

I find the best/easiest gains are had by getting fuel and spark in 
Proper order, setting your CO and ideally having a wide band a/f ratio 
meter around so you can make the neccesary adjusemtns to the EHA in an 
accurate manner...these cars LIKE their fuel @ WOT..  Not quite 911 
turbo rich (10-1) but in the low to mid 12's makes Good numbers.
