Gonzo,I haven't had time to do any tuning yet,but I did use the stop light dyno,the Tahoe walked all over a LS1 powered Camaro SS.So I guess I can recomend the GT2-3 402 combo.

 

OK we need old cam specs please,do you feel like you lost anything with the much lesser duration,I gather you did this swap for driveability reasons.Tell all the difference you have noticed so far,and do think it will require much tuning? I gather this was the only change you made at this time.

 

The old cam specs are 228/234 .588/.598 115+4 with 1.75 adjustable rocks.I'm sure that I did lose some power at higher revs,but I don't think I lost any power in low and mid-range areas where you do most of your driving.I do have a slight bog[I moved the idle to 750rpm with no other adjustment]just off idle and it feels like I need to add some timing and I did gain about 1lb of boost it's showing 8lbs.I may try to dyno after I get my tuning done as a baseline for the new supercharger.
