Unless its an error in the exhaust sampling, the AFR is leaning off quickly as the revs rise, indicating that you have reached the maximum duration time of the greys. As said for now turn the boost down to no higher than 28psi, as this is the maximum I was able to map the car to. Above 28psi it started to lean off after 5500rpm.
If you're interested I can simply remap the car on some 750cc injectors and a 5 bar map sensor if you want to ensure reliability at higher boost levels.

400-420 is well enough for me Karl,well happy with that
think i will save the 5 bar and 750cc's for the escort mk.2.
don't need the escort cos to have any more mods,well,not meaning more power,safer mods yes but then again i could just turn it down a bit more as it will be a second car when the mk.2 is finished.

he did say about it and said about the intake temps etc...they were a bit high.
Jay also has said exactly the same as you about the afr being high,hence more power etc..
thanks Doug.

oh and remember no 150mph private road racing until you get that top end fuel sorted

I'm sure 430-440 bhp was seen in the 80's on std RS500's, with just a remap for the 8 inj's.

Here's the link regarding the setup on the DD rollers.
Its about half way down on page 1 where "Pat" talks about how it operates.

you dont have 477hp but you do have a lot anyway .Mark
mark- also now means i'm tempted to bolt on a GT30 onto my stock motor for more grunt
...out of interest what HG you using dave and also MARK what sort of strain would this put on a stock motor ie std head etc as i thought the head culdn't cope with this power wihout being ported slightly????

I'm lost now 
how come some people with modded heads are having to cap the boost yet some with the same turbo and similar boost levels with a standard head arent having any issues?
your setup sounds spot on for someone on a budget, granted a T4 isnt cheap but compared to a full on rebuild with all the right bits its fucking cheap

are you sure the exhaust housing is the same size as everyones.
mines bigger than a .63.
its a standard rebuild Matt if all goes wrong with it, with the power i roughly have...400-420 lol, then why bother with the money mods and when something goes wrong it then cots a fortune to get a standard engine to the spec you have been used to.
i'm happy with the spec anyway.

So where i did mine,they would have been better not putting the temp sensor in the air filter....where would they have put it then that would make the rolling road safe.
they did say that the evos were better suited,as Mark said also.

I think APT just have the sensor hanging up in the Booth so it just reads the Air Temp. If its to close to the filter it will pull the heat in from the engine, this will make the computer think the air is hotter than it is. Then it will over correct the readings.
Thats how i understand it anyway mate, might be totally wrong.

Ah, never thought of that
So what housing do you use and whats the initial spool up like? I know you do alot of trackdays so lag/boost threshold probably isnt a big issue for you, just wondered what it was like on the road?
Sounds like exactly what I'm after, only the T4 doesnt put me off like it does most folks.
