i recently turbod my gsr running a chipped p72 with a base map i created in uber 1.66. the car runs great at 5 psi i put a homemade boost controller on it upped boost to 8 and the car feels like it hits fuel cut and runs like ---- any reason why i thought stock map would be good till 11psi is it my crappy boost controller or am i doing somthing wrong? there are no check engine lights car just kinda bucks and feels like its cutting out

 

well no ------- ---- ------. you tuned the car for 5 psi. you up the boost without adjusting the fuel. gee, i wonder what happens when I force tons more air into an engine without adding more fuel.

 

lol i thought that the basemap that i made would allow me to turn it up to 10psi judging from the injector duty cycle still reading alright at 10psi and it looking to be consistantly adding more fuel at that level. i richened it the same throughout that map so i figured it should work i still dont get why it wouldnt if it is adding more fuel up top. its at boost fuel eff. of 112 all the way through the boost map maybe i should just keep adding more ---- it was rich at 5psi and linear progression of fuel added above that

 

check to see if you have boost cut enabled and did you gap your plugs down to 28?
