I've seen heaps of 7-12 psi tunes where it flows clean through to the rev limiter... What's wrong with not recommending a port job if the boost is already controllable?

If I can get boost to max out at 7psi I'll be happy. Will try the 5psi Spring that came with the iwg75. Will back the preload off a tad. If still over posts I'll go the ported housing. Trying not to have this become a money pit. The damn big exhaust system has proven to be a headache. Up side is it sounds great. Link to comment Share on other sites More sharing options...

Ideally you want the wastegate closed as long as possible to maximise the drive pressure on the turbine (for response) and then you need the port to flow enough in the midrange to prevent overboost, but still enough control (from a decent spring rate) to prevent the gate blowing open up top. If you have any post or pre turbo aiflow mods and want to use your TS IWG you'll at minimum need to get the tune adjusted to suit and potentailly you will need the port job. FWIW I really like they TS actuators. They need slightly different approach to set up and tune than a stock garett unit but IMHO the higher mass of the internals helps improve spool up and give a smoother curve (assuming mech conditions are correct to support this) 1 Link to comment Share on other sites More sharing options...

I'm also interested to know how many of these cars you've setup and tuned with a ts iwg especially a b series car with a stock wastegate. Im also interested to know how simply adjust preload will help with a car that overboosts at peak ve then drops off up top? Link to comment Share on other sites More sharing options...

Just like when keith commented you let loose because you COULD be wrong.. I didnt say it wasnt 100% wrong I said I dont completely agree carry on... :/ Who's upset? I just asked a couple of questions and asked how you would deal with a particular scenario to better understand your knowledge and experience level?
