Hey I'm really hoping there is a simple solution to this problem but then again i'm prepared for the worst.

Basically my car now runs sh#thouse on boost. Driving around town feels normal and fine but as soon as you give it a little say over 50% throttle, it holds back, and feels like its labouring - like being in to high of a gear, then kicks in and drops out again. It only started doind this in the last day or so, and previously it had been running real well on 11psi since the new pump and safcII tune. But now it feels like its going into R&R type of mode or something real early in the rev range - from about 2000rpm. something is definately wrong, boost still ramps up to 11psi but the car feels DEAD - as in overtaking would prove an issue...

Any ideas??? Anyone encountered this problem before and fixed it???

Mods are listed in signature, plugs were re-gapped to .8 when i had the cooler done. It was fine before, so some existing part has stuffed up i would think.

Any help would be much appreciated - I'm sick to death of this thing being so temperamental.

Yeh all possibilities i guess that i will have to look into. Thanks to those who replied.

Thing is i just came back home now and it was driving like normal again... :P but it did it yesterday as well for a bit, so it seems very temperomental. When it was doing it earlier this afternoon it was quite warm, i popped the bonnet to check all the vac lines etc for leaks (none found) but i touched the front of the pod and it was damn hot. The pod itself is stainless steel so i guess it heats up quite a bit (un-shielded) - bad i know... shame shame. Could it be as simple as this?? As in requiring a heat shield for the pod and a clean of the afm possibly?? I noticed that some people are not very convinced on the stainless pod's filtering potential (blitz). I havent noticed it doing it when the whether is cold, but thats purely cos the problem has only seem to have arisen in the last couple of days, and haven really been testing it in different conditions. Would sucking in really hot air be the problem maybe?? perhaps amongst other things like plugs etc...

just a suggestion - make sure you have the right spark plugs , as far as hot and cold tollerance . many problems can arrise if they arent the right type . clean your AFM out with carby cleaner - look into some modification around your pod - to prevent excess engine heat entering . im currently in the process of trying to get my pod lowered down into my front bar if possible. saving me making an enclosure , and hiding the pod from cops.

Could be a lose connection to a sensor, was it doing it before you had the pod filter on there?

Pods been on there since i got the car, so it had been running fine for the most part previously. Just seems odd cos its not like i have changes something ecently casuing this to happen. It just happened by it self sorta thing. Perhaps certain components are starting to fail or need cleaning etc.

      Duncan's V37.......race car?

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.

      Jacks that fit under GTR lips that can reach the subframe?

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.

      BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
