problem with vortec 73mm

[Prophet]

If you guys are running the Vortec 73mm with the stock 24lb/hr sample tube.You are running lean on higher rpms.loosing horsepower.
19lb/hr sample tube will get you the right air fuel mixture.more power and torque.

IMO 73mm = Junk. I had it on my 93 and always felt it was holding it back. Just my 02. I know Scott dynoed with it, but just one of those things. I don't care what sample tube you throw in there, the electronics are not calibrated correctly.

I just received the 19lb/hr sample tube.
Installed[woke up sleeping beauty]
[WOW] the car feels great now, big boost from 3k rpm up.
Best bang for the buck[motor mod] so far.
