I'm planning on doing some upgrades to my 1990 300 has a e4od, looking for any ideas. this is also my daily. I do have a msd 6al digital, 19lb injectors, kn cold air, and cut the exhaust to in front of the rear axle. thanks guys

 

You need to tune the PCM to run the 19lb injectors unless you found another archaic way around the original 14lb injectors rated to run the 45-50 psi needed for the 300.

The 300 & 460 already the best CAI available with the air snorkel located in the radiator grill.
