Before I put the 2,93 pulley on, I already had a Magnaflow X-pipe & catback, cold air kit and the Predator performance tune installed, it felt very strong then,

So just today we put the 2,93 on and made the change with the predator to the pulley tune, right off the bat it seems to have lost some bottom end torque however the top is much stronger,

My worry now is have I made it unreliable? any one out there had any nightmares with the same set up?

It might be a good idea to get it custom tuned with the predator. It seems alot of people have damaged their 03's with off the self tunes from Diablo...and some other chips as well...

The only way to do this right is by using a dyno to see where you are at. To get by until you get to a dyno, just make sure you keep the fuel pressure up, and pull timing.
