After tweaking the car at Pettit the car is noticeably faster, has alot more torque, and is very responsive. But, im not quite sure the problem is completely solved. When cruising say in 3rd, at probably 2600-3000 or so I can tip-in even quite heavily and the car just seems to hardly accelerate. I can hear the turbo creating boost and watch it on the gauge but the car seems sluggish. Now, is this just me or is this normal. Seems that before I had these boost issues after replacing the motor that I did not have this problem....

 

Could this be ignition like before?

 

sounds like the 3k rpm hestitation, petitt should be able to fix it on your ecu. Is it a tuned stock ecu?

 

It is a M2 stage 3.

 

But I dont recall ever having it before...

 

ANY help?

 

How much boost are you getting? I'm wondering if you have a control system problem there.

My boost is great I get a soild 12 lbs on the primary, and then of course the spike me and you talked about Dale. I lowered the boost to 7 lbs last night by plugging the WG control, that way I dont hurt the motor while figuring out what to do about the spike....

 

May be a problem with the turbo precontrol - the exhaust flapper is open, giving both turbos exhaust pressure and giving more lag.

Any way that I can troubleshoot that flapper. I had checked the actuators with the rods before and everything seemed to open and shut properly...
