No power! Need help!
 

My truck seems pretty slow compared to other 12 valves, i got no plate and the mods in my sig, My boost only reaches 25 under full throttle and doesnt get up there that fast. Egts max out at 900 pre turbo, I dont know where to start? overflow valve? low fuel pressure? boost leaks? Its got decent low end power but almost no high end. My afc is tuned as well, need engine timing done maybe? Im lost help me please! :s:

I would check timing. mine was way off and was way under powered

What should I set it too? And would my timing affect my fuel economy alot, because I only get like 10 mpg in city? :argh:

yup 14 was my base on my truck I went to 15.5 and gained alot of mileage
