Well the "test pipe" has been on the car for 10 days now and I just got a check engine light. Code 0702 TW Catalyst Sys, yup it got me... Oh well whats the big deal with reseting the ECU every 10 days, yikes!

Because of my upgraded fuel pump and the inabality of the stock pressure regulator to control the volume of the new pump, my fuel pressure runs ~53psi at WOT and ~45psi at idle, this is about 17% higer than stock. I'm sure its robing me of some HP and making it tough on the ECU to control part throttle emissions because I am running rich. I have on order an adjustable fuel pressure regulator so I can get the pressure back down to specifications. I think this might help with the check engine light, but mostly the power levels at WOT will benifit.

Any ideas? (No I dont want to put the cat back on )

 

Which FP regular are you getting? Are you going to use it as a stand alone unit or in series of the stock regular?

 

I've ordered the Paxton EFI reg. and a regulator off fitting from JUN (http://www.junusa.com/parts/engineaux/regulator_off_fitting.htm )so I can tap into the fuel rail, I dont know if it will work but it looks like it will.

Since I need to go down in pressure I can go through the factory regulator
