Exhaust Boltons Dyno, Opinions? Somewhat disappointed with the numbers, It's a 99 so I know I don't have the LS6 intake. I was pretty happy with the dyno last year, but not so much with the one this weekend.
10/04 - 309RWHP/324RWTQ (Lid and TSP Catback)
9/05 - 319RWHP/331RWTQ (Lid, JetHot LTs, TSP True Duals)
This seems awfully low to me, as I was expecting to at least hit 330, plus $900+ for 10 RWHP just pisses me off, no matter how good it sounds. Anyways, here's my dyno sheets can anyone find any problems spots or give me some reasons for the low numbers? I think I'm going to take it back to the first shop and have them dyno it for dyno consistency. Also I was thinking about a tune, but the A/F Ratio looks good to me. Any opinions or suggestions welcome
10/04
9/05
Thanks in Advance

What was your a/f at? That doesn't seem too far off where my 00 SS was when I dynoed it a while back with pretty similar mods.
With LT's ORY lid catback and running WAY LEAN I put down 323RWHP and 329RWTQ That was running lean with a ported MAF though
Have u had a tune to correct for the LT's?

No i haven't had it tuned yet, im wondering if the SAE csmoothing is too high and hiding things. The A/F is on the most recent one at around 12.4-12.7. I was just expecting a little bit more, maybe I'll eek out another few with a tune.

First off, its not always about peak numbers. compare the dyno graphs and look at each rpm segment and see what you gained through out the entire curve. Also, when you add lt's it usually causes the car to go way rich and or way lean, so a tune would definately help.

Is this car Auto or 6spd? I have the mods in my sig and put down 314/343 unlocked through the decent sized converter and my cars been tuned also. Not always about #s, take it to the track and see what it does.
