Guest fripon Posted November 5, 2012 Share Posted November 5, 2012 As already said, sounds like one of the valves are not working correctly and not letting the second turbo work properly. I would avoid driving hard as you may do some damage. Does it feel like its surging a bit after 4000rpm? What does to boost to? yes she does surge a little after 4000 rpm Quote Link to comment Share on other sites More sharing options...

Bailey. Posted November 5, 2012 Share Posted November 5, 2012 Switches the second turbo on, there is a guide here somewhere of how to switch vac lines to test the turbo setup in Non sequential setup. Without seeing it I can't remember it off the top of my head. Quote Link to comment Share on other sites More sharing options...
Fizzy T Posted November 5, 2012 Share Posted November 5, 2012 I've not even driven the TT Auto Supra I've bought yet lol I hope I don't have issues.Been stood five years It's bound to have a few. Hope you sort your issues bud. Quote Link to comment Share on other sites More sharing options...
Scooter Posted November 5, 2012 Share Posted November 5, 2012 I'd read up on true twin conversion TTC etc and try that out if you are confident with playing around with the vacuum pipes, there is a massive sticky thread all on the sequential turbo system. If you are desperate pm Ian C with the promise of a half marathon donation and he may be able to give you some pointers. Quote Link to comment Share on other sites More sharing options...

Abz Posted November 5, 2012 Share Posted November 5, 2012 Even a stick TT should be rapid up the whole rev range, if anything you should feel a stronger pull when the second turbo kicks in. Check out some video's on YouTube to get a rough idea. In future when you test drive a car, demand a road to test the car properly. If the owner isn't happy with you giving it some welly then get them to drive it. I always ask if some different roads can b driven on, so bumpy roads, small roads, roundabouts & dual carriageways.

AndrewOW Posted November 6, 2012 Share Posted November 6, 2012 It's a bit of bad luck if you've been sold a TT that needs some work done to it. I just hope that whoever sold it to you may have known the 2nd turbo was dodgy, and disabled it by pulling off a vacuum pipe. I hope you get it sorted, but even a stock TT auto is a lovely motor, and would leave your GT4 well behind on full boost. Quote Link to comment Share on other sites More sharing options...
Yakky Posted November 6, 2012 Share Posted November 6, 2012 Superchip is an advance on the timing on most cars. It's an inline box on the wiring, and pretty obvious. It's a fag packet sized design. It will be between the ECU and the engine, probably where described under the passenger side carpet. Pull the box. It's probably causing a little bit of knock and knock sensors are pulling timing. These boxes are BAD news - worthless junk. Remove and reconnect wiring. Do at least this first before blaming mechanical VSV etc - return to stock.
