k im boosted d15,uberdata,step 7 plugs gapped .28, 8psi 14b hf manifold...when im boosting the car runs fine but when i left off the gas and give it anywhere below 30% throttle the car jumps and jerks a little like it is stalling after this happens the idle drops to around 400 rpm and trys to stall out i have to keep the foot on the gas around 1000rpm to get it back right..what is going on im throwing a code 7 on p06 which is tps and im throwing code 3 which is map sensor? what could be causing this fuel filter, fuel pump,fouled plugs? comptest yeilded 165-170-170-180 and like i said when i push it past 30%throttle it runs fine? help please.Also I have my fuel increase in boost on uber at 115 and ign retard at .7 im getting about 10miles per gallon? wtf

 

i'm also experiencing a similar problem and up to this moment i haven't found a fix yet or figured out what's wrong with my car.

everytime i hit full boost and let off gas then step on the clutch while still in gear the engine would stall, if i shift it to neutral right away after taking my foot off the gas pedal, the engine don't stall but rpm will drop to near stalling and stays down for a couple of seconds before jumping back to normal. if i gave it some gas it will have some bucking and drives wierd. if i don't like to wait for a few seconds for it to normalized, i just switch the ignition off then starts it again and everything will be back to normal.

i don't know if this is a UD problem, bin problem or tuning problem.
