I'm looking at upgrading my injectors and fuel pump.
I can't seem to find a replacement pump recommended for the 3800 series II.
I did however find this link:

I'm upgradin the MAFS, as well as the cold air intake to accomodate the increase in boost I anticipate. And it appears I'm going to go ahead and do the pulley drop to a 3.2". These changes so far as my research has gone will give me the air I need to handle the larger injectors.. I just need to upgrade my fuel pump for the higher RPM range.
If I'm in error with any of this, please do let me know. I'm still a learning ignorant at this point, and any advice would be appreciated.
As per the safely modding thread, I've already replaced
belts, thermostat (180), plugs (cold plat), wires, checked the intake gasket. Mechanic swears it's aluminum and in good shape.
replaced the fuel filter, and transmission filter. replaced Tranny fluid w/ straight Dexron VI, and the supercharger fluid as well.
I couldn't find any headers, speed daddy or not.. I've pretty much decided I'll get a custom exhaust to do a little straightening and drop to a 3" after the down pipe.
I'll start there, if I need more room to breathe later I'll address it then.
Someone tell me I'm not screwing up here, or if I need to take certain precautions. Advice and / or criticism is welcome.
Thanks in advance!
