Its overkill for anything that doesn't pop it.. Your stock head gasket should do up to about 350ft/lbs of torque... Its just not smart to replace good components..

Enthalpy tune and GT28 of any flavor and you have reliability..

 

ok cool, i get what your saying...last question whats everybodies opinion on the safc? should i get that as well as the enthalpy tune or will the reflash cover everything?

 

for my 240 I have a JWT ecu with SAFC-2 on top of it

 

Just tell Scott what you've got and he'll take care of it. You won't really need a SAFC.

 

I use an SAFC on top of my Enthalpy tune, but mainly for the Dec air fuction. I think the ECU tune alone would make close to the same power I make now..

You shouldn't get an SAFC without getting a wideband, so you are back to $400+ which is almost the same cost as the Enthalpy tune.

 

im not really worried about getting the safc for power im more concerned of reliability and if it will save me money in the long run

 

Power and reliability go hand-in-hand..

You should read on tuning a little. It will make decisions like this much easier.. I can't possibly post every answer in one post nor can I post everything you need to know.

Besides that, its not always the best idea to just listen to someone else the whole time...
