popping noise while spraying
Just installed a 5177 kit, 36 lb injectors, walbro 255 intank FP, on 5.3 heads with the TSP 233/239 cam. Took timming down to 24 Deg. and added a bit a fuel. Tonight was the first time i used it, and i was at the track..
first problem.. couldnt hardly fell any additional pull when the WOT switch activated.
second prob. Car was kinda popping and sputtering.. then on the shifts, it backfired and when i let off for good, it backfired..
Thought maybe my install on my Walbro had problems, so i pulled it, and the hose supplied with the TSP walbro kit MAY be too long, causing a crimp..not 100% sure yet..
Anyone got any Ideas?

Also added TR6 plugs with all the other stuff (forgot to mention) Car was tunned for larger injectors. Havent checked the WOT Fuel pressure, thats one of the checks im going to do today.

Funny how too lean, or too rich, or a misfiring plug can cause similar popping symptoms.
I'd check the plugs very carefully and if that turns up nothing put a wideband on it.
