Installed the delete pipe and tuner last week. Note to self: don't believe the videos on you tube. Have a gasket and EGT probe on hand. Otherwise, the underside stuff went well, even with the northeast rust on some of the hardware. This is my first experience with anything like this so I was fairly nervous doing anything that screws with the computer. The Gearboxz programmer talks you through the entire process and keeps you informed as to where it's at such as: Upload 25% complete, upload 50% complete, etc... Set it on power level 3 which is 70 HP over stock. Pulled the 5ver (15.5K) this weekend and there was a noticeable difference in power. This is the first time since the B23 flash that I've seen the boost pegged. Short pulls,(about two hrs each way), getting 8.7 MPG hand calculated. No complaints here since my one and only objective was NO MORE REGENS! Overall quite content with the venture.
