Low dyno numbers w/ 228R
I just got my car running and I feel like the numbers are a little low. I put ~100 miles on it before the dyno.
It's a 98 LS1/T-56 w/ 00 heads out of a WS6 T/A and no egr
-ceramic coated 1&7/8" longtubes
-228R on 114lsa w/ PRC dual valve springs/retainers
-magnaflow dual 2.5"-to-3" y-muffler to 3" out (no cats)
-Spec 3+ aluminum clutch w/ aluminum fidanza flywheel
-3" intake w/ rubber and aluminum couplings and a 3" K&N cone filter
-TSP mail order tune
-ported/shimmed LS6 oil pump
-LS2 timing chain
The dyno pulls were made in 4th gear w/ no fan up front. Um... I guess I just expected more power after reading a few threads on these boards. It seems a little lean also (but it smells REALLY rich at idle).
Any suggestions???? Maybe the exhaust is too restrictive?

I had a K&N cone bolted to the MAF for the dyno pull, so that's definitely a possibility. I called TSP, and they said to check for vacuum leaks around the intake manifold w/ carb cleaner.
I'm installing a wideband soon and borrowing a friend's hptuners, so I'm studying **** on the hptuner boards all this week at work.
Thanks for the replies fellas!
