mellonman Posted January 13, 2012 Share Posted January 13, 2012 NO unless you have the fueling changed to acoadate it correctly, covered many time search and you will find its called ttc Quote Link to comment Share on other sites More sharing options...

Tyson Posted January 13, 2012 Share Posted January 13, 2012 (edited) I believe there is a problem with fuelling around what would be the transition from the first and second turbos.

johnny g Posted January 13, 2012 Share Posted January 13, 2012 TTC would work best on VVTi's where an aftermaret ECU can advance the timing in the off-boost areas of the map. Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted January 13, 2012 Share Posted January 13, 2012 All you get is more noise and more lag. Thats pretty much it. Quote Link to comment Share on other sites More sharing options...
Gaz6002 Posted January 13, 2012 Share Posted January 13, 2012 All you get is more noise and more lag. Thats pretty much it. More predictable drivability, easier launches, better MPG. Quote Link to comment Share on other sites More sharing options...
mellonman Posted January 13, 2012 Share Posted January 13, 2012 people normal try this mod when there is a problem with the stock squencial,and then like it because it might better suit them, but thats because most times there was a problem with the squencial in the first place,there is a thread showing a dyno plot somwhere showing there is a boost spike and lean spot when in ttc. each to there own but no real gain unless you have a ecu to take benafits from it Quote Link to comment Share on other sites More sharing options...
a98pmalcolm Posted January 13, 2012 Share Posted January 13, 2012 TTC is POOP! I did it last year and thought it was god awful.. Put it straight back to normal.. Quote Link to comment Share on other sites More sharing options...
Kris H Posted January 13, 2012 Share Posted January 13, 2012 i got mine in TTC with all vsv valvs removed from exhaust and turbo piping, and i love it sounds and drives like a small singel=) i also got it mapped with Apexi ecu, dual intake,hks type R fmic, Quote Link to comment Share on other sites More sharing options...
Ian C Posted January 17, 2012 Share Posted January 17, 2012 There is a world of difference between going parallel with proper boost control and an ECU of sorts controlling the fuelling, and just jamming open some actuators and letting god sort it out. The first way changes the way the car behaves and you can get some interesting midrange gains. The second way merely introduces buckets of lag, unpleasantly lean running, and a nasty boost spike at 4000rpm. -Ian Quote Link to comment Share on other sites More sharing options...
