Just recently installed a flip chip that has JDM's warm weather program on one side and it really pulls great. It was designed for the warmer weather to try and keep the performance levels up because the warmer air will slow the trucks down. I have no track time or G-tech numbers but the seat of the pants could definitely tell the difference. The best thing about the program is that I took it out this morning in 38 degree air and tried my best to get some detonation and there was none to be had. The truck pulled the hardest I have ever seen it pull. This is a great overall program.
Here is a link with some more info on the program.
