Turbo lag? someone explain?

[dorift maestro]

here is my situation

just got a s13 BLACKTOP SR20DET in my s14 and drove it for about hour.

i drove it little bit normal and testing it out

first when the turbo spools the rpm goes up when it spooling and bov sounds off as i shift to second and so on to fifthi drove it around for about an hour and i start with first and feel something is bogging and stutter feel and rpm goes up really slow and felt no spool but bov still blew off the air

so i parked and cooled down for 5 minutes and drove it again and it drove fine and rpm went up fast and felt turbo spooled as first time.

i am not sure what this is but i think i heard this is some issue with the turbo lag?

tell me if i am wrong i just got it installed and i am running on smic and stock fuel pump

thank you

you might wanna upgrade to the walbro fuel pump..stock fuel pump isnt really cuttin it..also are you running rich at all? if you are running rich you may want to try cleaning your maf and checking the voltage on it as well..also check the voltage of your tps at idle and. w.o.t. throttle

Yes it does. If the fuel pump is not supplying the adequate levels of fuel the car will bog.

My car did something similar when I had a boost leak, but you said you checked everything out, so if your all good then you may want to look else where.

stock fuel pump supplies enough for for a Stock 7psi T25 SR. My vote is for a boost leak as well.
