[Syty] loss of power

[Bill Calcagno]

Sounds like you are overboosting.  Does the "check engine" light come  
on for a few seconds when this happens, then go out?  If so, that's  
another confirmation of overboosting.

Did you remove or "core" your catalytic converter?  If so, the  
reduced back pressure, combined with the too-small wastegate hole in  
the stock turbo, is contributing the problem.  The problem most  
commonly shows up when the weather gets cold.

The three most common solutions for this are (not in any particular  
order): use an external wastegate, port the stock wastegate and  
install a larger valve puck, or get a larger turbo with a larger  
internal wastegate.  You can try adjusting the stock wastegate rod a  
little longer, but that may not make any difference (depending on how  
it is currently adjusted).

		Good Luck,
		Bill
