I recommend if you do the cooler and UBP, prepare to drive off boost until the custom.I would do them both at the same time as you already have the bumper off and the UBP will take you another 20 minutes to fit rather then the 2hours . that's my opinion. OzzieYour giving me conflicting advice there.... Im still going to be running the stock tune. Custom tune will not happen till next year.I realise the UBP will be a quick job while ive got everything apart. that's why ive waited for my new bumper to be ready to go, so once the old one is off the I/C and UBP and new bumper go on in the one go. Ill just risk it, ill fit the UBP along with the I/C and see how it goes. If it overboosts then ill fit the stock UBP back in. I hardly every get on boost anyways, so driving around off boost isnt a problem. Edited 22/11/07 05:13 AM by hanra Link to comment Share on other sites More sharing options...

whistler6 Member 417 Member For: 17y 4m 30d Gender: Male Location: VIC Posted 22/11/07 06:41 AM Share Posted 22/11/07 06:41 AM I put my process west stage 1 cooler in a few weeks ago, my cars otherwise stock with just K & N and F6 intake and it runs fine, no overboost..But I chose not to put the PW UBP as I thought it might overboost, so I think you'll be safe with just the cooler until u get more parts or get a custom tune.. doesnt take that long to take the front bar off.

Maybe 1 or 2 psi overboost but it was the UBP that made teh car run like poo before I got a custom tune.The car still ran but it spluttered and carried on until I got the custom tune.

Sasha Member 141 Member For: 17y 5m 20d Gender: Male Location: North Queensland Posted 29/11/07 12:52 PM Share Posted 29/11/07 12:52 PM Overboost ?? Im not sure it happens as easy as you think. You will have to to add a bleed tap, or have the hose come off the wastegate actuator without you knowing to have it happen. I have done the K&N filter, Airbox, Capa Cooler, Full 3" Exhaust and had nothing of the sort happen nor seen it happen on any mates cars, so I say go for it buddy Link to comment Share on other sites More sharing options...
