Title: Boost issue?. Had enough!
Post by: K7RSX on 22 December 2013, 14:33

Hi, I seem to have a boost issue with my car and to be honest it's rely starting to annoy me

When I put my foot down the car feels slow all the time then when I'm around 4500/5000rmp it suddenly boosts?

I had a Cupra r 225 before with this issue and it was the N75! So I went out and spent £70 on a new one for my golf GTI anniversary 1.8t 180bhp and it's exactly the same

I've ran it with no maf also cleaned the maf, I've replaced the spark plugs/coil packs/ fuel filter.

Any ideas guys? :( I've had it on the vag.com and the VAS the we use at work and no codes. I'm running all standard just a full stainless decat exhaust. Many thanks

Id check boost pipes for any splits etc.. and check your recirculating valve/ dump valve incase its fooked

If is was a big a55 split u would prob hear hissing noise.. but most time no you wont... best get silicone boost hoses as standard ones are just sh1t anyway.. but course dont throw money at it till you know what it is :wink:
