Sorry for no update for so long, had to take the family on vacation and that got into the budget. It did allow me to run several tanks of gas through my truck to get some before hand mileages. 12 is the number right now. Based on a 70% around town ratio and 30% highway use. It is getting the headers installed at a buddy's shop and it goes straight to muffler shop from there. I decided not to do it myself on these to items strictly due to time. I have a throttle body spacer and full tune-up supplies that will go in as soon as it gets back from muffler shop. I will then do some new mileages. Hopeing for 14/15. That would put me in a good spot until I do electric fans, re-jet tbi, and regear it. I might just get to 18 if I guess right on the gearing. Any advice on correct gearing?
