full throttle hesitation
I did the mods in my sig a few weeks ago and my car just started hesitating at full throttle. It's not very noticeable but what it's doing is cutting out ever so slightly repeatedly. I thought it may be my fuel injectors not being able to keep up but this just started happening so I'm not sure. any ideas?

RE: full throttle hesitation
did you change the fuel pump? maybe its starting to die. throw a fuel pressure gauge on it if you can.

My pump is kinda loud, I suppose I might just change it out anyway. I will throw on a pressure gauge, what should it be at during idle?

I think I had some bad gas. Threw in some octane booster and voila.

10 degrees base. I got down past quarter tank today and it started lurching past 2500rpm. topped off the tank and it seemed to get better by the time i got home. hopefully it's just bad gas.
