Vaccum Leak???
WHOOPS WRONG FORUM!!!! MOVE PLEASE!!!
I just built my GSR for boost. Its a fully built motor just installed it 2 weeks ago. I'm using a GM 3 bar map sensor and 880cc injectors. I have skunk2 pro manifold with 70mm TB portmatched. Motor starts right up, then starts to surge from about 1k to 1,500k rpm. I've checked for vaccum leaks, cleaned the IACV.
Also When you hit the gas fast like if your going to rev it to 3k rpm... it boggs for an instant before revving.
Could the surging be caused by a Basemap not being tuned?
I have not set the Timing either.
If anyone has had experience with this problem please shed some light. Thanks.

I have no CEL's or anything.
But having them switched would definently give you idling problems.

Yes they could be possibly switched since the plugs are the same.. I know mine aren't switched because I looked up the colors on the harness and wired them to corresponding 3bar map sensor wires.
I have no CEL's or anything.

Wouldn't this cause a CEL having them improperly plugged in?
