its probably boost cut occuring, my car did it with just exh intake and downpipe everything else was stock. mine was barely getting past 12.5 psi or so (not exact) and it would occur. remember you may be at a different altitude than others and your sensor might be accounting for that. if you measure your voltage from your map sensor I believe the cut should occur at or around 4.28 or 4.29 volts, it might even be 4.3 however if your reaching that then it definitely could be a possibility and shouldn't be ruled out.

Are you sure those eradic points in your dyno aren't caused by spark blowout?

custom 3 1/2" downpipe, Blitz Nur Spec single all the way after that.

I'm going up to the shop today (National Speed in Wilmington, NC...really great place.) to ask some questions about accuracy for all of us who are interested.

Im pretty sure its the coils or boost cut (meaning I would need that cut chip), because I just changed the plugs around 8 months ago. However, Im going to get these ones that are perfect for the 2JZ, one of the numbers of the model I have is a 6, apparently I need a 7 or 8...:grin:...I found a set of all the coil packs used for 100 bucks, new ones are 400...used it is.
