Looking for a little advise. I have a '05 F350 6.0. Other than blue spring upgrade and coolant filtration system it's stock. Bought it in '13 at ~90k miles now at 178k. Did have the FICM go bad in '15 and the tranny replaced in '16. I do have a 36ft Toy Hauler (~16k lbs loaded). I've used the truck as both a daily driver and to tow/haul. Over the last few yrs I have noticed the mpg go down slightly (~14 hwy now, was ~16-17 when I bought). I've also noticed it seems to have more turbo lag then it used to (I assume carbon build up not allowing the vanes to fully operate). It had sticktion since day 1 (I control it the best I can with full syn oil and friction modifiers (rev x, archoil, etc..) and a periodic seaform treatment before oil change. Its still there, but I guess its managable with engine warmup. I've Recently considered getting a newer F350 ('12-19' w/ 6.7) based on these issues and its age, but that's gonna coast me $40-45k and I'd rather spend that kind of money else where.
So here's the question, should I leave the truck alone and just keep going or do I spend $5-6k to see if I can push another 7-10 yrs out of it? If so what are my best options?
Here's what I was thinking:
ARP Stud kit
After market turbo (garrett powermaxx 2 with wicked wheel)
Maybe a new exhaust (4 inch and remove the CAT, I'm in Louissiana so I'm not concerned from an emmisions standpoint)
And maybe a tune
What about injectors? Leave them alone, replace, could they be cleaned?
