martyc Posted August 19, 2015 Share Posted August 19, 2015 Hi guys, The last couple of days I've found my turbo spooling at the slightest touch of the throttle, like it's practically impossible to drive off boost?? First I thought it was being heavy footed but even the lightest throttle movements in 2nd or above sends the boost gauge into positive pressure (even if it is only 0.3 bar) and letting the d/v blow off on gear changes. It's not over boosting, max recall on the gauge is 1 bar, but never seen it going above 0.9 under full load. I don't recall it doing this before, and it still seems to pull cleanly and hard when needed, the only thing I can think of is maybe there's a post turbo exhaust leak lowering the back pressure? Anyone have any thoughts or feedback? Sent from my iphone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Tidgy Posted August 19, 2015 Share Posted August 19, 2015 sounds pretty normal tbh Quote Link to comment Share on other sites More sharing options...

stants Posted August 20, 2015 Share Posted August 20, 2015 I'm with tidgy on this, normal load I see 02 bar upwards on the slightest of acceleration above 1500rpm. What type of boost gauge have you got & where have you teed into ? Could be a gauge issue ? Quote Link to comment Share on other sites More sharing options...
martyc Posted August 20, 2015 Author Share Posted August 20, 2015 I've got the prosport stepper tee'd into the d/v line. I'm sure it's only been the last couple of days because I consciously drive off boost til the engine has warmed up Sent from my iphone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Tidgy Posted August 20, 2015 Share Posted August 20, 2015 At idle it will have negative boost, at low revs will go up to basic waste gate pressure, that why you see a little boost. Quote Link to comment Share on other sites More sharing options...
stants Posted August 20, 2015 Share Posted August 20, 2015 It sure how true this is but u was told the best place for most accurate reading to tee into is as close to the manifold on the intake side as possible ? Quote Link to comment Share on other sites More sharing options...
