Normally, if the ECU sees boost of more than 15psi (11 is stock) it assumes something is wrong and shuts down the engine until boost drops again, by cutting off fuel. This is fairly dramatic, and lights up lots of warning lights!

 

Pete's gizmo raises the level from 15psi to around 18psi (it's adjustable), which is generally seen as the highest level you should run without fueling mods. Other makes tend to completely remove the cut, which can be dangerous if you overboost drastically, as the engine will run lean and lunch itself. There's some more info on Petes website.

 

Fitting involves cutting a wire going to the ECU and soldering the unit in between, and splicing it into a power wire. It's pretty easy as long as you're confident soldering wires with not much slack.

MM me thinks ill let someone else do it!!!,

 

So its an overboost chip then, ok!, anything else, I saw the turbo timer but is it neccesary?

 

I thought they only kept the car running when you switched it off, so as not too F^&K up your turbos, Will i need to set a max boost!, ..... will it really boost that high on stock turbos and the mods im making! but if needs must then I guess ill get one! is HKS the best?

 

Cheers

It's easier than you think ;)

 

As for turbo timer try the Blitz dual TT it also has a boost gauge which you will need if you don't already have one.

You'll probably be OK with the front cat still in I guess but better to be safe.

 

You don't need a turbo timer as such, but I like the Blitz one because it measures boost too. You could just get a normal boost gauge and put it where the clock is, or in the eyeball-style air vent. That's what most people seem to do.
