i dont think anyone would suggest anything except a powerfc looking at your list. If all you had was an exhaust, FMIC and more boost then an SAFC is perfect... add a few more goodies like you have and any piggy back is not going to cut it like a full independant ECU

The new apexi safc has also just been released :unsure:

It's on nenguns site

bah the new acf neo is just a fancier s-afc, not much more.

in the end its still a maf manupulator, which suck, i learned that the hard way...

pfc is only a few bucks more than the afc neo so why short yourself.

I wudnt of thought with an rb25 wit cams the to4e wud of been THAT bad? My mate has a HKS to4e which comes on full boost (18-20psi) by 4,500rpm, on an rb25 that would be lower and again with cams, but maybe the hks/garrett turbos are quiet different or i have the model number mixed up and its just a to4 or somethin.

Define 'laggy' in ur opinion...

As for tuning make it a power fc no question. You can also tune it for abit less lag if you spend some extra time on the lower rpm's.

This may be a stupid question, but I was reading about the Power FC, and noticed that the Power FC can run the car using a MAP sensor instead of the AFM. Does the car have to be tuned using the MAP sensor, or can the Power FC be tuned using the AFM?

thanx guys for your replies, I ordered a power fc and waiting for delivery :blink:

hope you like lag, as the t04e certainly will be. why not go for something more suitable? whats your power goal?

I think that with these cams the t04e would spool earlier, my power goal is 450hp, what do u think? will i reach there with these mods and good tuning hopefully?

    • Each to their own I guess  Me, I put just as much time into cleaning inside of the cars as I do on the outside As for getting wet, it is really no different than steam cleaning the carpets at home, apart from the cars carpet dries alot faster than the house, again, I only do it in the hotter months and leave the car opened up for a few hours As I only do it yearly, it is just before I do the diff and gearbox service, so I clean the carpets, then it's up on stands, wheels off, service, clean the undercarriage,  grease the bushings and do a nut and bolt check on everything  Disclaimer: I typically had all the time in the world to kill when I was working 🤣, so spending a full day or 2 cleaning, serving and "looking at stuff" was,  easily achievable, and a fun mental therapy day As for time to kill, I retired last Wednesday, so apart from my physical training, my days are filled with lots of random jobs around the house and garden...."Idle hands are the Devils something something" I am also buying a new house sooner rather than later, I'm actually looking at a potential property tomorrow, I'm looking forward to getting a car hoist as I'm starting to get to old to crawl around under a car, I can only imagine all the undercarriage cleaning and looking at stuff when that gets set up
    • Yeah, I'm not interested in wetting the carpets, and I don't care about brown dirt/dust that lives deep in the pile or underneath. It's not like I crawl around on them in my birthday suit or eat dropped food off them (because there is never any open food in my car). The seats are alcantara (cheap Chinese imitation alcantara, to be sure!) with barely 1" of foam pad behind the surface. That's not getting wet either. Any car that I would be happy to get the interior wet, I would not care to put the effort into.
    • We have one that holds 2.8L of water. On floor carpet that hasn't been touched in 2 or 3 years, will take a minimum of 2 fills of the tank to do a bedroom, and that's going AROUND the bed.   In the cruiser, I used an ENTIRE 2.8L tank, just on the front passenger footwell. But it had some fungus growing, and had been full of mud from being used as a 4WD for many years. I can do that floor again, and it will still pull mud out. However, the water now only looks dirty, not pitch black and leaving full sludge in the bottom of the tank it sucks back into. Oh, and, this is about a $1500 unit.
    • This is mine, works a treat for the cars, suction is good, I use the Bissell clean and protect stuff I have found giving it a good spray and light scrub with the soft brush on the head of the nossle for carpet, and a rub with a microfibre for cloth seats and cloth door trims, prior to another quick spray before vacuuming it up works the best @GTSBoy You would surprised on what it gets out of carpet and seats that actually "look" clean, I recommend that you test drive yours when you have a little time to kill, then post pics of the muddy looking water that I believe you will find
    • I think even the "commercial" capacity ones that you would hire from supermarkets etc wouldn't have the capacity to do all that much in one go. I will go through half a dozen tanks of solution and dumps/rinses of the waste tank for one little 2 seat sofa. Or similar for one 6 footish rug. That's the price you pay for something small that only takes up a bit of cupboard space, instead of something that takes up the entire laundry cupboard or half the shed.
