if it were a fuel problem i would imagine it would happen all the time? i could be wrong. i had a similar problem and it ended up being a monster of an exhaust leak. ---

i had the same issue, no acceleration, like it hits a wall! mine ended up being my oil pump that starved my head and was causing my valves to only open part way due to wear on cams and rockers! i would check compression just to rule out that ---

I had the same problem, it was a ka, but it was ignition. I advanced the timing slightly and changed the wires, and it was gone. I know u don’t have wires but maybe the plugs are gone even if they look ok. ---

I think it’s a massive vacuum leak. Most prolly an intercooler pipe. ---

lots of intake leaks, especially the ic hoses at full boost don’t show up with a boost leak. I’m telling you ddue, check to see if it revs past 5000 off boost. ---

Yup same shit happened with mine. Stock sidemount shit kept blowing off and would not drive worth shit with positive boost. ---

Did you fix the boost leaks? Did that get rid of it? If not see what the wideband is saying when you install it and post up the results. ---

Have you changed your fuel filter lately? I know its a simple thing but a clogged filter will slow delivery. This same thing just happened to me i ran some shit fuel through it after i did a tank swap. Car ran fine for an hour then what you said was gutless after 4 or 5. i just changed the dirty filter and its running great. ---

i have a similar situation with my ca18det but only on a higher boost setting. i have a t28 bb and a greddy profec b boost controller. car pulls fine at base 6 or 7 psi when the system is off, fine at 9 the low setting and 13 the thing takes a quick nosedive at like 5 grand then goes right back to pulling hard… i havent run the car since last yr on the higher setting, till the other day and it feels like it looses boost for a quick second then right back. i coundt actually read the boost gauge when it happened becuase immidatley my eyes go to the road to make sure its still going straight. ``` things i have tampered inbetween last yr running high boost and the other day cleaned that idle valve on the side of the intake. ``` loosened the adjutster on the bov so it would go off easier, no chopping on the turbo disconnected the battery , therefore having to reset the boost controller… was actually running 14 psi last yr does yours just bog out for a quick second like mine or 5k rpm and higher??
