messing around

[powerstrokelover]

Took off my intake nose cone so just the filter is there. Also took the cat out running straight pipe back ending at my rear door. When I get on it it chugs and "misses". Any ideas? Might just put it all back together.

Fuel pressure is my guess. Could be an FICM problem though as well. You have any gauges on it?

[powerstrokelover]

Tested FICM its good. I wanna do the blue spring upgrade.

[RRF985]

Absolutely do the blue spring upgrade.

I have. It's an insurance policy for your injectors. This is a Ford upgrade, need to keep fuel pressure up. Low fuel pressure isn't good for injectors.

You can sell this to your wife by telling her how much an injector costs x 8.

A lace with the upgrade:
