All i can say is i have had enuff of this thing. Does anyone know the secrets to this thing before i spike it off the damn wall. We messed with it forever and it keeps dropping boost. cant keep it to hold steady.

Spike that POS. Thing is worthless for all the headaches it has caused you.

PM-Performance

im getting close, but no money for a new one

What do you have the lines running to? If your running it from the turbo try running it from the IM. I have heard of people having troubles with their Spec 2 when running it off the compressor. I had no troubles with mine at all, literally took like 15 mins to get everything set up and works perfect.

aznballer

i got probs with mine also, i liked just the wastegate spring, then it would boost constatntely and not fluctuate

Arturbo

Here is a secret, get rid of it.

ive had alot of problems with mine , but ive had alot less problems with this than teh AVCR.......

M.A.R.C.

ahhhh... good old profec b for me. i dunno man but a lot of people have had troubles with the spec 2.

MONTCO Si

im about to ditch my profec b and use the GM boost solenoid to run off the aem ems and set my low/high boost setting off of their...heard its a million times easier to set up

Thats funny as **** that Zac, my customer here says this. I have been working on his profec b spec2 for a couple days now. I finally got it work decently, but still fluctuates about .5 psi in low boost and a little more in high boost.

Art is right where he says "Here is a secret, get rid of it."
As for a tuner, I find that I lost time and money trying to get the pos to work for my customer.

Zac, sell that piece and we should do the $15 GM boost solonoid. You'll be much happier......me too as soon as I explain to you how to control the ****.

PM-Performance

Thanks to B18CYA , we talked it over for a little last night and the way he explained it seems more simplified than the instructions. I will try it out again tonight on the dyno and see if i can get it working .

the lines are right, its the settings that are acting up

ATS*Mark

let me know what you do to fix it man mines getting ready to bounce the hell out

PM-Performance

didnt you post this great How to Thread on how to tune it not too long ago?
Pete who is now even more confused

ATS*Mark

who me?????

no i posted on how the hell do you tune it!! and it helped but didnt get it like it should.

b18prl

you saying 1 is better than 2? because i'm thinking about getting one of this but don't know which one is better.

This really sucks. I just bought one. Why couldn't people post some of this information when I asked before?

boost junky 71

I disconnected the pos. Spring holds boost just fine and no damn overboosting. If anyone figures it out let us know.

t04ecvc

We have tuned a few of them, they are a little tricky in the beginning. I prefer the first one tho, i will never get rid of mine.

turbo*s2k

I was using the greddy profec b-spec, and sold it because it wasn't consistent. Good luck getting it dialed in... Are you getting boost spike or having trouble hitting a certain psi?

Sivik

i got the SPec 2 as well and for the most part it'll hold boost. slight drop off but it took hrs to get it right. high boost setting holds better than the low boost one too. but i found out how to get it to hold....

no cat.

i took off my cat for some drag racing at the track (ran open header) and i guess due to the decrease in back pressure it held boost solid as a rock.

only problem for me is that from time to time it resets on its own and i have to re-program it. anyone else?

RedTT

I've never had a problem with the spec II. There have been people that had problems with boost dropping at redline but here is how you're suppose to hook up the wastegate

middle nipple- inatake mani
top nipple- stepper motor

and here is how you route the bs

in nipple- boost source right after turbo (very important)
out- top nipple of wastegate

Many people don't hook up the boost controller's in nipple right. If you hook it up strait to the intake manifold, your boost will drop in the end

HOLY ****!!!!

RedTT your car is awesome! I thought it was just gonna be a nice little with body kit and factory twins on it, boy was I in for a big surprise

Seeing that you are new to H-T I think you should share with us your car and all its mods. I know I for one would like to see and hear more about it!

Good job on it

Ace.

Very true...a very common mistake made by all tuners alike...

karmannghia

If you could draw a diagram it would help a lot. Because I hate my spec 2 also.

Get an HKS EVC4 less than 250 bucks on ebay, they are EASY to setup and dont require the guess work on the spec2, my friend has one and all i can say is that damn thing causes more problems than it worth a major PIA to setup and it never holds the settings. The best thing about the HKS is you DIAL up the boost you want and your are done. If you boost higer than what you set it for you turn the OFFSET up, boost lower turn the OFFSET lower, none of this % crap.

Good luck
