Do you mean the Granatelli twin-flow air box ??? I have one of those--they work very well--as the others said the granatelli MAF--toss it and put the stock one back on--I have found that the corvettes are already pretty finely tuned from the factory and the most I've gotten is about 10-17 RWHP with a tune--With the air box and exhaust it will help to get the fuel trims back closer to "0" as all that stuff has a tendency to lean it out--The ECM will be adding fuell at PT so when you go to WOT--it will be a locked positive in PE which is not what you want--but all this stuff isn't so bad that it will throw codes just not be as smooth--If you have an A4 then I would deff get a tune to work on the Trans. settings--alot of performance is hidden in there especially with the TQ mgmt.,shift times--shift at VSS and sihft at rpm--TCC lockup--base pressure,abuse mgmt,
