Cheers for the replys, very good info. Gunna check voltage at afms this weekend. Have a de-cat pipe on there, inspected the front pipes as best as i could when they are on the car, and have new HKS filters. The car is running better since changing the exhaust etc. Will see what i can find out over the weekend Cheers John

Cheers, will have a look

Hi guys, Sorry for this being my 1st post, but thought someone maybe able to help out of this one. I've had my 32 for over a year now and had some issues but some great times. It pulls well and i thought was full of power for a low tuned example (spec below). Anyways thought it was time to get a health check and power run to see how things were. Engine spec RB26 with std internals (as far as I know) Std ecu Std boost Driftworks wasted spark plug kit Up rated plugs HKS twin filters De-cat Apexi (Jasma) exhaust Went to a very well known company who deal with a lot of race car tuning etc. and was expecting 300-330 hp. But got 230bhp!!!! @ 5200 (power just fell off! and 466 lbf.ft of torque! (which seems very high!) The graph The guys said it looks like the its getting 'strangled' top end and they suspect its the exhaust...they have found that Jasma spec exhausts can cause major restrictions. So have replaced exhaust with a Japspeed hi flow cat back system.....but no change! (Altho it seems a little easyer to drive!) The cars also seems to be idling very high (around 1600 rpm) had a hunt for vacuum leaks etc with no results! Have also played with idle control valve and AAC, disconnecting both with no change! So my question is.....um what’s going on lol...have i got 2 problems???? Any help would be great. Cheers John
