s14 sr20 problem

[S14steez]

hey quick question i just changed the timing for my redtop sr20 and everytime i try to haul ass in each gear it feels like my car wiggling back and fourth so i dont know if its my fuel pump that i need to change because i just put a new catback on it with a apexi muffler any reasons why my car is acting weird like this?

what did u change in timing? like ur whole timing chain and gears? also did u sure u put the cas on right u? timing is what causing ur car to act like this u prob didnt put it back to oem specs

yeh the timing in gears and no i didnt but everytime i put my foot on the gas it lags and my cars kicking like im coming out of a bad shift but im not shifting you think it could be my turbo? Or my fuel pump?

i just put a new oem catback on it with apexi muffler and it's an all stock car with stock sr20 just a nishimoto intercooler and cold air intake so im guessing it should be my fuel pump idk though any tips on what the problem is?
