ninetyNINE...welcome to the party!

Most of the free mods suck...hence why they are free. The two that I did were the EGR cut down in the upper intake manifold and ditch the coolant going through the TB. Keep the screen in your MAF and the EGR restictor seemed to work a bit too.

Also '99 are the most detuned of all trucks stock, suffer from false knock, and have a smaller cam than the '00+ ones. A tune would make it run like a bat out of hell compared to now.




01tunhder...I too plan to tune my box on the 30th too. Maybe I can get rid of that stupid converter lockup at 30mph!
