Dyno Time Again Lastnite

[Angus Smart]

So after fixing my problem with the car i got the car on the dyno again lastnite. (hose clamps and hoses)

still getting my loss up top. and worse when i have the old profec a boost controler on it which i think is just a problem all together.. this run was with a bleed valve..

now the loss i am getting up top could be from my plugs which i need to change as there is a miss fire up top.

but when on stock boost the run is very smooth power is a nice curve with no problem and boost is a very flat line. only when boost is up it does crazy things up top.

my standard dumps are probably causing some backpressure up top and could be adding to the problem.

p.s. car was run in 5th gear. not 4th like graph says!

afr is up the shitter too starts up at 14ish then goes off the scale below 10..[

the boost deffo looks wrong. it's on 10psi at approx 3000rpm then spikes to 21psi, then back down to 18 or so. i hope the turbos can handle 21psi!

i think they can? its only about 1.5ish bar right?

so i think i'm going to drop the engine out. maybe over xmas or something.

change timing belt, plugs, fix seal around front diff, check out what rod's or rod bolts i have, fit the new dumps. and if i can get a new boost controler i might give that a go.

then a definate tune is needed with my afr's haha
