Sell the stage 1 and spend $370 on the diablosport predator. I bought one, and I love it. Diablosport predator is cheaper than a stage 1 pcm, and gains more power than a stage 2 pcm. I have an aem cai, fm wga, stage 1 injectors and predator with a custom tune that was made for free since I bought the predator through ragetek. Here's my dyno sheet. I'm a 2003 and my only fuel mod is stage 1 injectors. Also, ignore the boost graph at the bottom, it's not correct at all.
Custom rage tune. (spiking 15, and holding 15)
I love how smooth the powerband is, and how strong it is all the way to 5500, even on stock turbo with only 15 pounds all the way. Blue line is 3rd gear, and red line is 4th gear.
