New Project - Tuning my 3.4L for POWER

[insite]

i was reading over some chatter about a similar issue on another forum. one guy said his AF issue was solved by raising his fuel rail. he was using the boxster fuel rails w/ the 996 injectors. when he raised the rails to the right height, his AF problem went away.

this doesn't make sense to me. anyone see what i'm missing?

(FWIW, i know that the 986 & 996 injectors are identical. my personal solution was to modify the 996 rails to work on the 986, so this issue is not a concern to me).

Fuel pressure and injector setting differences in conjunction with intake airflow differences....just a thought

ltft should adapt to all that fuel stuff unless it is out of adaptable range, at which point it should chuck a code. freaky maf readings due to turbulence or pressure beat waves should also trigger a code. i think either the 02 sensors are off or the computer wants it to be at 10:1 if it is running that way without codes.
