Hi had my car remapped everything was fine till today giving it some and when i hit 6000rpm its juddering and as if its no power

 

Forgot to add i disconnected the maf to see if it was that and the car kept running didnt cut out reconnected took it back out and it run ok is my maf maybe causing it

 

Go back to the mapper and get him to check it. That's what you paid for. He will find the fault a lot quicker than you could.

 

as above, dont play guessing games.

 

Cant see it been anything to do with the map as its been running fine since i had it mapped until today

 

up to you if you want to throw a new coil pack and maf on it or find out from the mapper if its boost cut/fuel pump etc. Your choice, we can only advise.

 

i would check with andy forrest as above peter

 

I sent him An e-mail grant but just thought someone would have had the same as andy wont reply for a couple of days

 

Ok guys when i use full throttle and hit 4000rpm
It gets jerky as if boost is cutting but if i accelerate at mid throttle its fine

 

ah, that makes it a lot easier to diagnose.

Replace the fuel pump
Replace the maf
Replace the coilpacks and leads
clean the boost control solenoid
check the turbo actuator
then contact the mapper.

 

****ing hell Mexican you've got me in tears here mate!!!

 

Look can you not read i sent andy f an email waiting on a reply so does that mean i still cant see if anyone has had the same problem

 

nice attitude. Maybe you'll take the hint that 119 people have viewed this thread and only 2 or 3 have offered advice. I've given you a GENUINE list of things to check, if you want to go down that route its up to you.

Based on what you've posted, its an accurate diagnosis.

 

All you had to say was check the items and leave the bit about the mapper as i already said i contacted him but he takes a couple of days to answer im sorry about the a** bit

 

People on here can't give you a seriouse reply with being arrogant or a sarcastic ****!

 

Peter, has it ever had a new fuel pump? what you describe sounds like fuel starvation, which is NOT good as it causes the mixture to go lean, and THEN you get the dreaded det, which kills Scoob engines quicker than you can type about it

 

Yes new hrc pump rest of the mods are
Full 3"decat
650cc injectors
Td05-20g andyf
Aps induction
Silicone intake
Mapping went fine and it only does it with full(open)throttle not when i accelerate normally
Andy thinks overboosting or intake sucking suck

 

The only things changed from last map are the turbo and silicone intake and the car made 396bhp 370ft/lb torque

 

Am I reading this correct Peter?

You had it mapped, then changed the turbo and inlet pipe?

 

No mate had my Vf35 mapped before the wanted more power so changed turbo for the 20g and silicone intake the remapped again for the changes

 

Gotcha.

 

Mine runs a HS TD05 20g, and I was advised to use 740cc injectors.

Are yours maxing out?

 

I will check with andy thanks for the info

 

ok found out what wrong when mapping i had a air leak i found it after mapping so sorted it andy says it over boosting so back for map tweek

 

thats good chap, at least you didnt try self-fixing it by spending money and replacing un-necessary parts. Got there in the end and it didnt cost an arm and a leg.

 

Thats true mate i now know instead of swapping parts and again sorry mexican i was just a bit pissed as the car wasnt running right

 

No worries fella, glad you got sorted. I understand the frustration, cars are a "mans" thing and when they go wrong we all think "its gotta be something simple" but then when its not you start tearing ya hair out and the toys go out the pram.

Unfortunately, these cars arent like the old skool cars where there are only a few things that can go wrong. 1 thing can lead to another, and another and thats what I was trying to steer you away from. Theres soooo many people on here who post up once theyre £500 out of pocket and still aint fixed it so at least you did the right thing and asked 1st.

Hopefully you'll notice a difference after the tweek as you've not been getting full potential yet

 

Thanks mate for understanding
