The 400 Mission

It's probably causing the misfire in cooler climate as your boost will be more aggressive and I think you said you are still running standard valve springs.

Probably find your springs are starting to fail and your number one cylinder is the worst affected.

If you have done the springs, then I would be thinking your number 1 coil pack is a bit low on power out put.

Or as said could be a doggy spark plug or maybe not gapped correctly.

You may only get the miss at cooler temps.

Go for a early morning run to recheck if it does it again.

If it does cheapest option is get a new plug and at same time switch coil pack 1 with coil pack 2. Retest.

If its fixed it then you know coil is ok and plug was cause, if number 2 shows fault then replace coil.

If number 1 continues to show fault then I'd be checking valve spring pressures.

hey mike are you running the mods of a 3566r .7 front cover bigger wheel 1.06 rear housing or standard 3588,,,35/40 with dump

standard 35/40 turbo with external wastegate

My car on 21psi has been holding up well except the faltering valve springs, and the rear left wheel bearing had shat itself. Im holding off on the valve springs as its keeping my fuel economy down at the moment by not putting my foot into it as much

[djqc]

got the valve springs done today at xft. simon wasnt really happy with 22psi, so gonna book in for a retune soon and let him work his magic

I don't care what the end figure is, but I do care that bought a turbo that is supposed to replicate the original turbo, and doesn't. It is a manta twin 3 inch exhaust with twin 4 inch cats, as monsta torque have seen better results with the twin cat set up. It's what they put on all of their cars so I'm guessing is a good bit of kit

My gtx spools the same as the old turbo with a apparently restrictive 3" intake/exhaust.I recon your exhaust is the issue.Full boost in 1st by 3000rpm and less in taller gears.

What diameter is your hotside piping bloke,mine made boost earlier with a 2" hotside compared to 2.5" aftermarket and still made respectable power for the boost used.

There has been a new tune and actuator put in the car since that post. It was once lazy but it has been resolved now. Im running the process west stage 3 cooler kit, so whatever piping is in the kit is what I'm running. Does my graph look similar to yours?

[GTEXXED]

totally different but that's expected considering variables.TBH,I asked for a tune that's best for powerskids so its a bit more torquey down low but nowhere near yours uptop.

next is to dump it 50mm

Looking good, looks slghtly familar, oh yeah I did my original 19" in black too. Such a pity these wheels won't fit over bigger brakes as they are a very nice wheel either in silver/50th accents or black. That paint job looks, even from the photo, first rate

Don't go too low though you'll lose some handling ability. Try and stay at around 345-350mm front and 340-345mm rear, you'll still get a nicely lowered look and not compromise the handling geomentry too much. If you afford it do Teins adjustable height and still pretty good quality shocks/springs.
