Hi i have a standard 1.8 t agu with a ko3. i have had a remap on it today. before remap the dyno showed me having 164bhp and only 140 lbs torque. after it shows 188bhp and 171lbs torque. im sure the torque should be higher. ??? Also car was running at 6psi before and is now at 10 psi...... the guy said to me i prob have a boost leak.

i have also noticed a loud whistling noise from the car when i accelerate. do i have a boost leak and if so how do i go about finding it??? i only ask as i wanna go k03s but want this sorted 1st. cheers ppl.

did he run vag com before the map to find the boost leak if so he should have not done it till you got the boost leak fixed that my thoughts coz i have been flipped in the past with people saying the can map cars and they cant they just want your cash

as for leaks check the pipes on the intake mannifold and underneth it

 i dunno if he ran vag com. he pluged lap top into it. can any garage use vagcom onto it or is it a specialist thing?? cheers

The whistleling noise you now here is the turbo now that it has that extra psi. The BHP figure isn't bad and you have to remember that the bhp figure will vary from car to car. There are several things you can check yourself like the turbo pipes as already suggested, but also check MAF, spark plugs as these two items can seriously affect the performance. Are you running a standard diverter valve? The standard items are known for splitting even from new and thus causing boost leak. If thats the case get a baileys (my fav) or a forge as most people on here go for. Oh easy way to test DV valve is to take it off and see if you can blow through it, if you can, then BIN it. If after checking all this then it's probably worth getting someone to run VAGCOM for you. Oh and if all is ok then it just may be that the map on your car isn't very good! And maybe you should take the car back to the company and get it done again at their cost. Must check everything else first for yourself to make sure everything is as it should be.

 thanks for info. i was told as my car is an agu you cant run vag com. if you can do you know where i can go to do so. i am goin to get a mechanic to look at pipes as i have and dont know what im looking for. i have not checked the dv its atd. i will take off now and check. how do i check maf? i want to put a ko3s on but want all this sorted 1st. then ill take it back to the place i got it mapped. what model dv do u recommend ? a recirc one or blow off? i want a nice sound. cheers mate

yes hun you can run vagcom on an agu.

i have a forge recerc dv. to be honest, its not that loud but aparantly its better for your turbo.

i also have a blow off dv in the house thats slightly louder but not much.

 do u know where i can get someone to run vag com? do garages have it? have you got the forge 007 one?

Check the vag-com section.  Loads of guys on here have it.  I'm in Scotland so can't help but there will be somebody closer to you on here.

i cant help you the vagcom, as with the figures that have been produced, the ecu needs a couple of weeks to get use to the remap and fuelling etc, but if you were to take it back to get it rolling road tested again, then you should see a change in figures.

 well i have left it two weeks and its still boosting to a max 10psi. im sure it should be higher. the guy who mapped it said i should put a bleed valve on it to turn psi up. surely i should just find the leek right? do u know where to go on here to find vag com? cheers

Got the splitr on my car and sounds quite loud (well enough for me anyway) Had it about 9 months.....

does your car run ok with it? my m8 had one on his ibiza and it ran like shoot.

i just think itl sound nice, and be better for my turbo.

i was really wary about getting it fitted as a lot people complained about atmospheric valves being no good for the engine, so did my research and couldn't find any people who had complained about it - the only niggles people had was that it wasn't loud enough. Don't know much myself but i do know that the pipes that fit to it, fit in the opposite way to the standard bosch one.

I have heard that if you want it louder you will have to get a cold side relocation kit.

All in all im am more than pleased with it, the little whooosh always puts a smile on my face! and as mentioned before, it's been about nine months since i had it fitted....

cheers hun. ive enquired about the cold side relocation kit, and the company that are doing my remap, sez that they dont make that much of a difference to your dv or the performance, its just a good way of getting money out of you...

the dv that i have on makes a slight swoosh but sounds nice when your sat in the car :)

 whats louder the 007 or splitter? is the relocation hard to do??

 

the 007 is louder than the standard one, but not really noticable outside of the car.

this is the relocation kit on a car.

go to http://www.dpmperformance.co.uk they sell everything on there, and damian is really really canny

 

 cheers will it be louder with a airfilter on it??

 also do u know where i can get someone to find my boost leak. its hard to find someone who knows what they are talking about lol. its winding me up. making me feel like selling the car and getting another celica lol

i have a k&n pannel filter, dont know if it makes it any louder coz it was on when i bought the car...

i dont know of any in your area hun and ive never had a boost leak on mine, so i cant help you on that one

Does the car make a loud hissing noise in the higher RPM's?

 with mine fitted with no other mods sounds pretty loud on the inside and from out.....

got these clips from youtube which kinda give you a good idea of how it sounds
