Question

Well now you have given us more info. runs poorly, not just backfiring.

If its N/A, Cap & Rotor = replace !

Misfiring is your problem. Why is the question. Could be a lean fuel condition.

if u get your hands on a backpressure tester ,hook it up on the o2 sensor orifice before the cat. I cant remember but it should be in the low 0 to maybe 3, cant remember but it pretty much should be steady on the verry low also during acceleration, there should not be much fluctuation on the gauge under accel..

First do a tune up! Plugs, wires, cap and rotor. Most of the time that is all it is. If you have a cylinder or two that aren't firing, it will have no power and buck and backfire. Try that simple stuff first then see how it runs. Air filter too.

is your car throwing any codes (engine light is on)?

if not then I agree, do cap and rotor, check your timing, check all your vacuum hoses for cracks or missing connection, replace your fuel filter, and perhaps test your fuel pressure.

if you still cant solve the issue, sometimes its nice to take it to a mechanic for a scope check. Its usually a reasonable fee and a good mechanic can usually figure out whats wrong for you. Then you can do the work yourself to save money.

Anyway, just a suggestion

no codes but i think i narowed it to a boost leak and it must be giving my car to much gas and not enough air because the air goes in the MAF then most of the air must come out some where on the way from the turbo to the intake manifold. But would it make my car flutter or wanna stall when i get on it or start moving? i got it up 2 around 5-6 rpm and the boost only goes to 4-5 psi
