Engine power Randomly cut off I didn't know where else to post this, but driving my car under boost it just randomly lost power. In other words, it felt like the throttle blade just shut. for a good 10 seconds or so it wouldn't allow me to accelerate and I was pulling over. Then it was able to accelerate again. I have a brand new racetronix fuel pump installed last year. I also replaced my TPS sensor, but I doubt this would've caused this. I will datalog to see what is going on. Does anyone have any idea what can cause this?

Resolved. Instead of chasing my tail, I just decided to get a dyno and tune done. Unfortunately the guy I went with was booked over a month. It was a tuning issue. The procharger complete kit with tune is a very great kit with great pieces, however the tune was way off. Way off. I would recommend people just buy the basic procharger kit without the injectors, booster pump, and tune and have a professional tuner who knows what they're doing get it dialed in. Also, get a fuel pump and fuel injectors yourself so you can have room to upgrade in the future. The ones I have on the car only have 15% room left for increased horsepower. The tuner I had was very knowledgeable and really helpful. Tuning is like a different language to me, but at times under medium to heavy acceleration it was basically flooding the engine with too much fuel. Luckily my tuner said it's extremely unlikely any hydro locking occurred. So this explains why it felt like power was randomly shutting off. It felt exactly like having the throttle blade snap shut immediately.
