more fuel pressure

Well Cloud, I would say this is true except for one tiny fact.  When GM (and
those other fellas) established WOT fuel maps, they did it to maximixe
power. There are (were) no WOT EPA standards to meet. The skys's the limit.
Assuming they made a mistake on there WOT maps, there might be improvements
in altering the A/F ratios. One Hi-perf. book I read, said that if there was
any SINGLE item on todays computer controled cars that could be changed
(without breaking the emission laws) to increase their performance, one of
the hundreds of engineers on site would have done it. Performance sales!
Would you by a car that advertised, "The Lowest rated horsepower cars in the
world...and damn proud of it!"?

When the FAQ is completed, line one should be:
Q- Can I raise my fuel pressure to inscrease my WOT power?
A- No. If you have a stock automobile, and its is working properly,
increasing fuel pressure (with no other changes) will not increase power.

Good luck,
GMD
