Hey guys in need of a boost controller. Don't know allot about them but need one before my tune.

What are people on here running?

I hear the greddy is popular

I can get the blitz spec s for 100$ less then the greddy Profec b 2. Which one would be the way to go?

Thanks in advance

for $100 less go the blitz.

basically the same EBC.

I have the blitz spec 2 in my car and it holds 20 psi with about a 1.5psi drop around 6000-7000 revs

which TBH is fine by me at that rev range ;)

one thing that is important to remember regardless of what controller you use is that be careful and aware of the pressure difference between the actuator or gate spring and what you want to run

ie if you run 7psi spring and you want run 22psi thats a lot of work for any controller and the results might be spiking boost / tapering off boost or inconsistent

you should run a spring that suits your "mininmum possible boost" and then use a controller to let you bleed a few PSI over that mininmum

ie if you want 21 psi then run springs that give you say 17psi minimum and bleed the rest via controller

and lastly if you see boost pressure taper off in the rev range its probably excessive exhaust back pressure (housing too small or boost too high)

I had a profec B which was ok until you start running over 20 psi.

as per above - any controller can let you run any pressure

ie 57psi if you like providing the base spring level is half reasonable

it sounds like you might have had the wasgate spring too low, ie 7psi spring trying to bleed 20psi

and/or the housing is too small or exhaust back pressure is excessive

even with a 15psi spring a small housing can yield poor boost control as well or "tapering off boost" is what most people see

and they usually blame controller and try to find a better controller that can hold boost

ive got a powerfc boost kit for sale to suit ecr33 for cheap

If you have a power fc this would be my first choice, my second is a Gizzmo ebc, i have one and it works great and is not expensive because it is only an ebc, does not have any other wank factor attached, i would recommend almost any other ebc before a boost T or adjustable wastegate, the way an ebc works much better than any boost T.

Edited by W0rp3D

there are a few additional features the powerfc boost kit has over a seperate controller

1 - plug and play no extra wiring or controllers

2 - boost displayed on hand controller

3 - boost correction is enabled on the ecu

4 - safety fuel cut if boost exceeds target by 0.25kgcm2 - ie split vac lines

5 - you can use the boost reading in logging if used with datalogit to better tune boost build

With an ebc set up right you don't have to worry about boost creep or drop off, personally I have spent the money on an ebc as its more accurate than the old hks adjustable wastegate I had.

thanks for all the replies

I ended up going for a boost t as my tune was brought forward and it was the cheap alternative to the space in time I have

maybe one day ill end up with an ebc as ones you guys have recommended

@gtsttrk - boost levels between 12-14psi

Yeah mate just FYI for down the track any of those controllers would be fine for those levels of boost:)

EBC can't be beat for maximum power and drivability, but for small to moderate power increases, the Turbotech boost T does an amazing job given it's cost. Never spiked or failed me in any way and I've never heard a bad thing about them!

    • Does it also misfire equally when revving?   Josh is very correct in what you should do. The coilpack harness wiring loom itself is a known problem due to its age and the number of heat cycles it has gone through. Throwing parts at a vehicle to diagnose the issue isn't a smart or good way to do it. Secondly, you may have a bad coil pack, you pop replacements in, they fix that issue, but messing with the harness breaks it, so the issue persists. So now you think "well it wasn't the coil packs" and have to continue chasing your tail, potentially swapping back in your shit coil packs and returning the good ones (yes, I've seen people do this because 'it wasn't the problem' and they want to save money). And suddenly, you've got two issues with the same symptoms...   Diagnose, don't use the spare parts shotgun.
