Went to dyno today for a baseline pull... I had a chance to put my vette up on the dyno today. I've got a fast 78, longtube headers, x-pipe with cats, and B&B bullet exhaust. My #'s after two pulls were 323 hp and 327 tq. Is this normal for a 98 C5 with the above mods? I was expecting a little bit better #'s than this. The car hasn't had a tune yet for the mentioned mods (I was going to wait until after I installed my heads and cam later this summer to get a custom tune). Any ideas?
Here's the graph:

Yeah that does seem low... my formula with the LS1 intake and MAC's (ORY) UD Pulley, P&P TB, LID, and a Magnaflow catback Dyno'ed 348hp 357tq to the rear a few weeks ago, Before getting it tuned it but down 337hp and 349tq. So yeah tuning will help.

I dont think that low really.. A 98 ls1 has the worst heads, add on top of that the car is going to be outa tune and i dont think thats really that far off.. get it tuned and i bet you would see 345-350 rwhp 360-365 rwtq.

The car has a little over 100k miles also. Could the tune be that far off? Could something else be wrong? The car runs pretty strong as is and doesn't burn oil, and still gets 18-20 mpg in town and 29-30 mpg on the highway. Not sure where to begin looking for potential problems. Any ideas?

Just as a comparsion my vette with a intake and cat back pulled ~325 on a dynojet, no tune. I would tune it since you added the fast 78 and headers, there is prob another 15-20 rwhp on the tabe with a tune
