At least i tried

have you checked all the items that would cause this..hayes manual goes a long way....vaccum leaks, BAC, Variable resistor, TPS...90% of the time is a vaccum leak....My advice, because this is how I found the solution to my problem, is to make a intercooler bypass pipe, in other words take the intercooler off and use some type of material (i used dryer ducting) doesn't have to hold under boost this is just so you can look listen and feel for vaccum leaks while your car is warming up....while looking grab a can of carb cleaner spray it all over the vacumm spider on the back side on the intake manifold also in the front right behind the alternator, and don't forget about the sileniods near the dipstick. if you idle rises while you spaying you've got a vacum leak in that vicinity.....My cuprit was 2 vaccum lines on both sides of the primary fuel rail....
