GBGTE POWER CHIP GARBAGE JUNK DONT WAIST YOUR MONEY Installed power chip tuner looking for more power. Don't waist your money!!!! Tuner chip burned my wiring so now I have a shorted harness shorted computer Shorted out injection harness Shorted out igniters burns them out in a matter of 10 minutes Had a review by warehouse was told because my truck was a05 so old that there is no way chip caused this on a 70000 mile truck I bought new that my truck already had these issues before I used their product So funny yet frustrating...so ask for a refund for the chip and won't even do that!!! Don't like giving a bad review. Companies like this don't stand behind there products Shop want to charge 3000 to fix my truck Company won't take responsibility for what this chip has caused to my truck

Because of transmission characteristics it was up shifting early and in slow traffic or slow uphill was pinging and suffering. After my first week trial I gained +/- 4 mls/gallon in urban traffic and +/- 7 mls in highway. Throttle response became amazing. Pinging and suffering at low speed still exist. In manual it says after two weeks it will work properly. I will share my second week.
