Hello everyone, im looking for some advice on pulling alittle more power from a 4.8 in a ecsb. I have all ready tuned it with hp tuners but other than that its stock. This weekend im going to install 4.10 gears and headers, which i have 2 diffrent sets. So my question is which set will the 4.8 benefit from, dynatech with cats or lpp with ory? truck has stock catback and was hoping to stay with that. I was going with the lpp's because im building a lq4 for this truck and i thought the 6.0 would benefit from them but that swap wont be for a while
