on 1/19/21Hello, the chip takes 2 weeks for it to be fully programmed in the vehicle. It will help with up to 40HP 20TQ so you will notice improvements in the 0-60 time. Thanks.
This is not true I have used their stage 4 kit. The timing functions did not work and any information it did give you could be read off your dash gauges. I can tell you how ever that the jet module i bought worked immediately.
