ok guys im new to dsm, done LOTS of researching and understand they are high maintenence but im stumped

ok i just got the car did a boost leak test at 20psi and i had 2 leaks in tb so i fixed them(didnt check and see if it held boost though)had to take pressure of for silicone to dry. anyways when i gas it it like builds strong to 3000k then takes a shit but the wierd thing is is that its built full boost by then 10-11psi is this normal.
1.has cracks in manifold
2.5yr old gas mix with some new
3."ported head "

mods
autometer boost guage
cutoff exhaust (at cat)
evo fmic
? wannabe greddy bov i think?
thats about it

could the 3 problems cause this or bad turbo or what thanks a lot

The first 2 yes. They could and you wont know where your at tell you get them fixed.

I think those are the least of your worries if you are revving the motor to 3000k

Bad gas will definitely cause this. Look into replacing the fuel filter also.

Cracks in exhaust manifolds are bad. Replace the manifold.

Ported heads are good. Don't worry about that.

kk thanks my dumbass self already replaced the fuel filter and then found out the gas was 5 yrs old so do i need to replace it again

i will inform you guys after parts are replaced .. hope thats it

Just do a tune up on it. Fuel filter, plugs wires, and fuilds. I bet you anything it will run better after it plus you can the peace of minds knowing everything is brand new.

 

[out there]

personally, my suggestion is to check out the cheapest stuff first - mainly, the plugs and wires. before my wires faltered in my saturn, i had no idea just how much difference poor quality wires could make

new
wires.(the guy said it had new plugs)?:/ arent you not suppose to use platinum or iridium
fuel filter
oil filter
oil
air filter




i think i have a big part figured out . my alternator is going bad so i just bought a new battery and it ran fine for like a day but i still DIDNT GET ANY POWER AFTER 3500K ? but when battery is about to go dead i get backfiring and shitty running (didnt know an alternator could cause that)

thanks again guys for the help
