I have the tuner on my 99 V10 and feel it is worth it. I run the 87 Performance tune all the time it really moves better now. Some say the 5.4 Engines don't respond as well though. Have you changed rear gear ratio?
Do you think the tuner is worth the money or just the y pipe?
It shifts better and the improved fuel tables from 5star for the v10 for the 10% ethanol that is at every pump around here no one even has an ethanol free 87 that you can pay a little extra for. I think it's worth it but I would try and find an unlocked a sct tuner somewhere online and then order the email tunes separate to save a few bucks.

No, I am leaving them 4.10s because im planning on doing a 12 valve swap in the future.

If i have a shop install the y pipe can they weld it with the exhaust on the truck or do they have to take it off the truck?
