Swapped out the Midpipe which had been crushed from hitting speed bumps etc. this primativelty measure tothe equivilent of a 2.5" diameter. I had a new new 3.5" midpipe made up by an exhaust shop. I put the car on SRR dyno on one of their Saturday Dyno Days, and Charlie advised it was running a little lean for his liking 12.8:1 AFR. I then took advatage of a few deals, a Syvec S7+ from Whiftbitz and 1000cc Injectors and Rail off a memeber, SRD made me up a pre-terminated sensor loom and sensor package, I got all this fitted. Long Story short - SRD Mapped it on all the new bits and it now makes 558WHP @ 1.6bar and 455ft/lb.

To revive this thread, this was the relay above the fuses in the kick panel that needed replacing ?

Where are you based ?

It sounds as thought the vacuum piping used in sequential operation is likely the issue you are having, I found sometimes the old pipes dont seal/seat well any more with the VSVs. I would then look at the VSV asscoaited with the sequential operation. You should be able to find the information on the forum for the VSV and piping that arent used in TTC but are in Sequential

Interesting that you asked this exact same question 2 years ago, why didnt you use that thread if you are still struggling. I would attach the leak tester to the air filter side, then put through a small pressure. are you looking for leaks in the boost piping or the vacuum piping. what is the problem you are trying to solve ?

I have one attached to an aristo box in my Garage in Maidenhead. I dont know where you are put you can have it, not sure I can be bothered to post it.

Lovely Update. enjoyed reading that with my morning coffee. Its nice to see a Motec vs Syvecs comparison for a UK Supra, not that I ever considered a Motec.

Maybe its for an aftermarket gauge ? It looks like the lower one is the one for air/fuel. Whats the setup on the car ? Does it still have the Stock ECU ?

Have you recalibrated both TPS ? there is guide in the Autobox group, it is an extract from the toyota repair manual

Really enjoying the updates, keep them coming. Nice to see the developement of the platform and see products I didnt know existed, the PHR fuel tank

Have booked in now

Its something for the power steering, the TT inlet manifold should have a provision for it somewhere ( I think its under the throttle body )

Oh.... I have the switch kicking around in toolbox somewhere. I have an ECU somewhere aswell

I guess yes with the traction control. The ICV would connect to the stock turbo intake pipework, on a single turbo you can just put a small K&N filter on it
