A faulty blow off valve and the way you have described your fix firstly has to be corrected.

Then get a new cat..if it is faulty.

You will then need to reset your computer...I think you are in limp mode

Limp mode Hey! Never Heard of it b4!!!

Only got the One BOV hooked up with the 2 vaccum lines running into it. The Other Bov is still on there but has a metal plate behind it so it won't let anything escape.

boost leak?

Reset the ECU? Certain mods (such as BOV's) can confuse the computer and make it run poorly..

something so small as plugs or cat are not going to make 20 - 50Kw diffrence..

When did you change your oil and oil filter last?

Has anyone worked on the car before it got sluggish?

I know of many stories of people leaving the rags blocking the turbo piping (so no sh*t falls in while your working on it) and forgetting to take them out before connecting the piping back together..

A/F ratios? how do they sit?

Check the faults in the computer..

Check your fuel pressure.....

Check your injectors...have them cleaned

Check your cat...

Check you have boost...and no leaks.

If they all are correct....borrow or buy a second hand stock computer..plug it in and see if this fixes your problem.

Good luck with your find.....hope it is just as simple as a cat or a blockage in your muffler.

Oil and filter Were Put in Just b4 the Dyno run so they have only done dyno time!

Said the Boost is Running at 11 PSI and he did tell me about the rag incidents today actually when he was letting me know about the problems!! was talking the car up that everything was running fine so i was getting excited until he said it got crap on the dyno!!!!! (car was originally in the shop cause it was Running to rich for some reason so i said wack it on the dyno for me and give me a tune. They also Run the Consult as well so i

'm not to sure how the A/F ratios.)

Compliance cats are well known killers of power.

Its easy enough to drop the exhaust before the cat and run it on the dyno again...or go for a drive and see if the car feels less 'choked'

Start with the obvious things like the exhaust before doing the smaller things. Limp mode is exactly that, LIMP mode...as in your car wont rev, wont make nowhere near 150rwkw and will be barely movable. Designed to get the car home from wherever you are, not cost you 20kw

Thanks for the info Bro!!!

And when you say Limp mode, how far will it rev when it is in Limp mode??

when i got mine done they were saying 150 to 160 is stock. i made 194rwkw and i just got exhaust n airfilters

it all depends what dyno you use though, you could dyno it twice in 1 day at 2 different places and get different results. not to mention you'll get a better score in cooler weather than in hot. they not the most accurate thing in the world. i mean why would they do 3 runs in comp's if it gave a perfect answer everytime.

you'd be best off getting someone else with a stock gtr 2 race you or get them to go down the dyno at the same time and compare the results then.

could be a low reading dyno. how do other cars go on his dyno.

my old SR20 180 got 151 RWKW with just catback, filter and 15psi. And i had a 1J with same mods got 180RWKW. (EDIT:Both on Dyno dynamics in shootout mode on dyno days)

      If it (the code) wasn't still current, it should have gone away by itself by now. No, nothing it 10/10. But it is quite likely. Everything else to do with the ignition could still be responsible (which is wires and connectors). The car is an old piece of shit now, so all the wires and connectors are also old pieces of shit.

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

      By Duncan · Posted

      Before I get to the test day, just to finish off the android head unit. This is a demo from car start up....the standard/host system takes a few seconds to boot (same as all v37) but Android comes up quickly. In this vid I'm using the delivered launcher but have set the default to Agami since which is easier to navigate when if use primarily 5 apps. You can see the host system still takes over when required eg putting it in reverse, and you can switch between Android and not by holding the back button 3 sec. It is pretty responsive (fast) but you can see I had to press harder than expected a couple of times.  I still have the phone connected to the stock system, and that also seamlessly takes over Android music playing. v37-android-demo.mp4 The bigger reason that I put this in though is so that I can use Ecutek directly on the head unit. That gives me a dash with logging (up to 20MB only), high and low value warnings on any parameter etc etc. I've run a USB cable from the Ecutek OBD dongle to a USB input on the unit, easy. v37-ecutek-demo.mp4   The unit did freeze on the launcher the other day, I think Agami was trying to verify the license when it didn't have a data connection...will monitor and report back if there are any other problems but so far I'm very happy with the upgrade.
