After the USPS losing it and re-sending it back to North Carolina it finally arrived today
I just recently switched both differentials to Royal Purple and Mobile 1 in the engine.
I have the K&N High flow drop in filter and a muffler delete.
Thinking my next mod is one of the following, need some input.
Cold air intake
LT Pacesetter Headers
Under drive pulley
I probably wont ever put a cam in.
My truck seems quick, Im running the 91 tune. Just looking for a little bit more power. MPG increase is always a plus.
Im leaning more towards the headers, however, I feel the drop in filter and simple muffler delete could be holding some power back.
