If I do put on the 33"s and notice power loss what are some things I can do to to make it run better for say under 5 grand as I also need to tow a 5.8mtr boat...
If you are going to be towing a big heavy boat, then as some others have said:
dont stick too much other stuff on your truck till you have really had time to get used to it and taken it off road (you might be suprised)
and keep the standard tyres for towing
For power upgrades without blowing your motor:
start with a better exhaust and performance chip and fit a temperature pyro into the dump pipe to monitor EGT so you are not cooking it when towing under heavy load for long distance is what kills these things.
next would be a boost gauge and possibly a Dawes valve if the boost is going too high.
Then better intercooler and bonnet scoop etc etc
So you can see that really it would be good to keep it standard for a while maybee the exhaust and EGT are a good safety feature to keep it running
and read the ZD30 reference information document on this site, it has heaps of great information.
