lol, Ontopic: i have no idea

 

maybe cuase its the same guy? =P lol

 

Do you have an after-market intake, plenum, or both?

 

He does, and a lot more stuff...

According to the sig anyways

Is your CAI sealing well?

 

That's probably the deally. He needs to check for leaks in his CAI. If there's a leak, the MAF sensor is seeing one thing but the engine is getting another. Use propane around all connections of the pipe, if it revs up, there's your leak.

 

okay i'll try this

 

but yup all i have is an injen cold air and thats it.
