Does my chip need to be modified if I change my boost level?

Simples....

I always have mine set by MSD and never change it until my next visit, did they set your car up?

 

That depends how much and how you change the boost. If you're just adding a bit of boost by adjusting a bleedvalve it shouldn't need it, as long as you stay belong the boost limit for that chip.

 

I don't have a bleed valve, was going to get a local tuner to set it and set the fuelling for me, but wondered if I needed to send my chip to msd to be altered.
I want to go from holding 24 to 30 psi

 

I wouldn't know what needs to be set for the fuelling. As long as you only increase the boost and the chip can handle the 30 psi you should be OK. But it's a bit difficult to answer when you don't tell what you current setup is.

 

Escos grp A T35 with mar-m, dark greens, 3 bar map, msd evo chip, ALS. Is there anything else you need to know? Presumed std cams/internals.

Just take your car to MSD it's cheap enough and you'll know the car will be bang on.

 

You won't be able to hold 30psi on greens on a T34 mate!

 

I'd did, but I had 8 injectors lol.

I'd do as suggested. Either take it to msd or another reputable tuner to get it set up.

 

I would say you would, almost certainly, as your current calibration won't be mapped for the higher boost pressure!!

Tried phoning stu at msd yesterday, but he is a very busy man!

 

With that turbo and increasing the boost the current injectors won't flow enough. So you will probably need different injectors and a different chip, since the chip needs to know what injectors it is working with. Best go to MSD then to have it set up.

 

The green 803s dont flow enough for that sort of boost, they usually peak at around 25-26 and tail off

we can do 55lb siemens packages that will allow you to peak at 32psi and run the turbo flat out to the rev limiter, but it still wont hold 30psi as the T34 compressor is to small and doesnt flow enough air to keep up with the engine at high rpm. they will naturally tail off to around 25psi at the limiter.

 

how much for the 55lb siemens packages?

 

Injectors are £250 a set, chips start at £250 and vary depending on ecu/spec
