Dave,

Thanks for the kind words. I've spent a lot of time understanding the 3.2L engine and how to really extract peak torque from these motors but the principles are the same for tuning most engines. Bottom line is set fuel in the 12.5 to 13.0AFR and then the magic is all in the timing. For those interested in really learning how this is done I suggest you buy both books by Greg Banish, search Amazon for him and you'll find the books. Those 2 books have the secrets easily explained and why ignition is so important to get correct. Best money spent getting those books, I also have him as a contact reference now and we chat engine dynamics from time to time. The other thing that's very important is knowing exactly how much air the engine is ingesting and you can NOT beat a modern day MAF meter for this as it measures Air Mass spot on! I run a lab grade hot film MAF in my car these days and it's amazing how well it works.

stroke (4mm longer) and basically the same CR. Little to no performance tuning has
been discussed for the 911SC as has been for 911 3.2. Sal, help these guys!

Note: Sal has his own performance chip for 911 3.2s.
