Change head studs before adding tuner?

[johnnyroastbeef]

I recently changed my tires to the larger 295/65/r20 Nitto Trail Grapplers. Love the tires but my acceleration isn't what it used to be. it's not terible by any means but i tow a 30' travel trailer in the summer and fall and wanted to add a SCT tuner to make up for the slight loss of power from the larger tires. I was wondering everyone's opinion. Will adding a tuner blow my head gaskets for sure? I'm not looking for a wild tune jsut a little boost in power. Thanks in advance. -JRB

If you drive normally it should be fine. If you romp on it everytime you accelerate, you are more likely to blow them.

You are just as likely to blow them pulling your trailer while staying stock. If they go have it studded when they replace the gaskets. With the 6.0 it's pretty much a case of when, not if.

this might sound dumb that i don't know this but is the factory warranty going to cover the new gaskets if/when they blow? i'm the 2nd owner of this truck but it only has 33k on it.

Yes it will. I just had my 05 done 1 month ago before my warranty ran out on Feb 24th. The EGR setup and head bolts are the weak points on the 6.0. Head studs and deleting the EGR make them fairly bullet proof. If you can't delete the EGR completely you can do a sneaky bypass that will pass a visual inspection but get rid of most of the problem.

I was under the impression that the warranty was for 100k miles, is it 5 years or 100k?

[PGreenSVT]

Yes, it is 5 years or 100k, whichever comes first.

isn't it heat that pops the gaskets? so if you have a pyro and keep an eye on it you should be ok, right?

No, they pop from the excess boost pressures from the added tuner. Yes EGT will cause excess cylinder temps. But they are not the 6L's issues.

Studs, EGR delete, Tuner. In that order. Reliability, redundancy, then performance.

i heard you can have studs put in a truck without pulling the cab as long as the head gaskets havent been blown. true or not?
