Well idk if it is ture about blowing you bottom end but if you are worried you could probaly buy low compression pistons. Also i head that bov cause to many code errors i heard that a diverter valve would give more preformance than a bov and you would still get that nice sound with out any code errors

How does the blow off valve cause code errors. Is it because of the instant loss of pressure every time you let off the gas that triggers a problem with a sensor that probaly monitors and controls pressure in the turbo?

well idk reeally but what i would sya what does it is liek you said
a bov let out all the pressure into the air whic will make you lose bost and will make you lose pressure and a diverter valve will take the boost from the turbo and then put it back into the manafold thus keeping the boost and not making you lose power and making less turbo lag

its b/c our cars use MAF's to meter the air.. a bov vents to the atmosphere and that missing air causes the car to run rich b/c fuel is getting supplied for that air.. a dv dumps back into the intake tract..

Ive asked alot of people and most have said that they dont believe in a boost controller for this car, why???? Also would a stiffer clutch and pulley kit be a wise choice? Ive heard of DBW but what exactly is it?

[AudI_MaN]

my bov vents some air back in to eliminate any problems. ive also bought a FMIC but havent mounted it yet because i need to organise piping and endtanks, but im having second thoughts as most results ive seen with and w/o a FMIC are similar, as the rest of the cooler would be expensive, do you think it would be advisable to go through with it?

mbc's will throw the car into limp mode... many have tried...but they never work out...

dbw is drive by wire.. there is no direct mechanical connection between the gas pedal and the tb.. its all electronic..

definitely run the fmic if you're going with a turbo upgrade... it may not make any dif in a dyno run...but if you're planning on tracking your car...the difference will be there.. or even multiple quarter mile runs.

my cooler is 15cm high, 600cm long, and 5.5cm thick, i could ditch it and go with a 600 long, 30 high, and 7.5 thick, but am worried that itwill be too big?????????????????

..stick with the small for now.less trimming and less pressure drop...
