Thanks man

If check engine light is on because of boost sensor problem would that be causing surging problem at steady throttle light cruise? I see IMS sell 4 bar boost sensor for barra. Iv read to do it properly retain stock tmap sensor to keep good low rpm driveability and upgrade to 4 bar boost sensor to tune it properly. Is this true?

Is the stock boost sensor at its limit, can you buy and get calibrated a higher bar map sensor for barras to fix it so it can adjust fuel and ign for higher boost?

@Puffwagon Ok thanks we will try that. Is that a common thing when turning boost up on a barra?

@Puffwagon I went for a tune with gtx 3582 gen2 today, got 432kw at 5800rpm and 867nm at 3575rpm at 17.7psi, 20psi at 3350 till 4400rpm then tapers off to 17.7. Anyway all was good on dyno. I drove away and check engine light came on and could only get 5psi boost and on light cruise car surges from 10IN-Hg to 5IN-Hg. Went back to tuner checked codes. P0236 and P0238 Turbocharger/supercharger boost sensor A circuit range/performance (current) and circuit high (current). What do you reckon? Is the map/boost sensor on the inlet manifold? Should I replace that sensor? Whats the one 9n the throttle elbow?

@Puffwagon does the fgx ecu log knock on a table that can be viewed? my tuner reckons he couldnt get a knick table to come up but older ba/bf ecus he can.

Ok I took it out and put 12v on it and it clicks so it must be ok then.

So the only way to test it is on dyno or road tuning to see if its ok?

@Puffwagon im testing my stock boost solenoid, its still plugged in to car and ignition was on but car not running, iv applied 5-10 psi air into the hose ports and air goes straight thru one port and out the other. Its not making a clicking sound either. Theres what looks to be a 3rd port on it with a black cap thing on it, what is that? Is it the vent? Am I testing it right, should I hear a click?

Thanks heaps man, I really appreciate the offer. Mine is on hp tuners, would my tuner have to get pcm tech for you to help us?

I will go to a shop, I havnt learnt to tune. Pisses me off my tuner couldnt stop it boost surging. Another dude tried too, no luck. It all started when I went from a tune of 382 kw stock crossover 10psi at 2500rpm 14psi at 4500rpm all was happy. Then to a hardcore tune 400kw, turbo side intake, 16psi at 2500rpm and it had a hissy fit which he couldnt fix. So im running straight off gate and its mint. Apart from having no electronic safe guards and I cant ramp boost in slow. Which is why I slapped on bigger turbo to get boost later in rpms and keep rods in.

My 4 inch dump pipe has got the stock o2 sensor screwed in it, that's all.

I made a new turbo water outlet pipe out of stainless fittings, a brass tail, and a short length of 10mm push-lock hose. I used loctite thread sealant on all the threads so hopefully it doesn't leak. I like it a lot.

Happy new years boyees, whether you stay ip till 12.01am or not. Im getting up at 5am to go milk 550 cows with my staff so def not staying up till midnight, il see new year in the morning.

@Puffwagon my current boost control is hose from comp outlet to wastegate, with a gfb turbofuse as safety pop off valve. Boosts perfectly as is. If I put on gen 2 gtx for arguments sake with bleed valve or harder wastegate springs to boost to 20psi (currently got 19psi springs and boosting 16psi, gate must be getting pushed open a little by exhaust gasses.) And set up the turbo fuse for 21-22psi I reckon it should be safe, what do you think? Also would it be better to leave my current 19psi springs in gate and run a bleed valve tap to get more boost or increase springs pressure in gate. Or does it not make much difference either way? Ofcouse I will get it tuned. Do you start with low timing numbers and slowly increase them when tuning while checking for detonation? What should max timing numbers be under boost?

@Puffwagon I have a new garrett gen 1 and gen 2 gtx3582r supercores in my shed, which one should I put on for running 98 octane only. Thought id shoot for 420-430 rwkw. Need to keep rods in motor, so kinda thinking gen2 could be better bet because it will spool a bit later with its 66mm fan.

Maybe he had a really incompetent apprentice that did a slightly poor job.

I did chuck 40 or 60 bucks in pot at one point in this journey after you guys laid on the guilts onto me in exchange for some turbo knowledge, but in my profile I cant find hard evidence of it. I just want to find out about old mate.

Yeah, the imagination runs wild. From what I had picked up his work was of a high standard, he even polished engine bays. Pretty hard to polish that turd on fb.

So what happened with JETURBO? Or is it top secret? Is no one allowed to talk about it here?

Is that map from $2 shop

I see maoris, that are in aussie that moved there from nz for a better life are now upset their fellow nz maoris now have to be equal citizens with the white man in nz, national, act and nz first won election and are kicking ass and are gonna sort out and ditch alot of pro maori policies that labour put in.

As a person who identifies as a straight dairy farming male, I can say that I found hilarious. Lol

What do you call a gender nuetral person that is lactose intolerant? Non bi-dairy hahaha
