So I am getting a 24psi HP tune on 93 very soon from TERMINATOR 2, and after being on here, I have noticed a few things people say are pretty mandatory to do before an AGGRESSIVE TUNE.
1. NGK IRIDIUM spark plugs gapped at .035" = $30set
2. DEJON bypass valve spring = $10
3. UPPER intercooler charge-pipe = $200-$300
4. INTAKE = $120 for upgrade tube/filter, $200-$300 for sr or ca intake
5. DOWNPIPE = $200-$300
Is there anything else people can add to this, or a response to the things I have on this list would be appreciated.

Well after some experience, I would say that the Downpipe, intake, charge pipe and intercooler are probably the best ones. No one has ever mentioned the Dejon spring to me. The stock AC Delco plugs are fine and are the same thing as the NGK ones so you might be able to save a bit there but not much.
Ask lots of questions. It will not only help you learn but it will also help your tuner understand what you want. Have fun.

the spring is supposedly stiffer and allows you to hold boost better, and the plugs are supposedly one-step colder for the added power.
I have the down pipe and muffler delete, but will probably get the ZZP upper charge pipe and intake tube as well as the plugs.

you can get all those parts for much less i would get them used and check out the for sale threads on here save yourself a lot of money
and yes like others have said the stock plugs are fine so you can buy fresh ones if you want and you gap them at .030 not .035
i wouldn't waste the money on the spring i would just either stay stock or get the forge bpv

Technically yes you do need the 3 bars for accuracy.... People have said yes keeping the stockers are fine but even making your custom Pid to see higher then 23lbs with the stock sensors you won't be able to see it correctly.

I think I just threw away my dejon bpv spring. If I would have known, I would have given it to you for free. Let me check if I still have it if you're interested.
Also, I'm curious about this 3 bar adapter. Is it plug and play?

The spring helps with boost leaks, if ur goin over 20-21psi I wud get it, I would also gap the plugs to .032 and there is no reason to get the 3bar, the stock hot-side pipe is known for crackin n poppin off under higher boost and is very restrictive
get intake, downpipe,charge pipes, intercooler, intake THEN tune
stick to stock bpv spring. if anything buy the forge bpv.
ive heard bad things about the spring.
stick with stock plugs, if you do go NGK plugs dont go one step colder. they tend to misfire and ****

My opinion, yes, that was the first thing I switched n technically u can buy one at a hardware store for like 3-4 bucks, its quick n easy to do so why not, I found out from my friend after I bought the dejon one about gettin one from the store
but still is it actually needed as always a matter of opinion, u got mine
