I had my car dyno'd for the first time. I figure I want some before and after headswap numbers. I was a little dissapointed with the numbers. 191.1 hp and 286.6 torque. I didn't really have any expectations but those numbers just seem low. With the following mods, would you say my numbers are high/low or just about right?
-Magnaflow X w/ cats
-Flowmaster 2 chamber catback
-Steeda U/D pullies
-K&N FIPK
-Accufab 75mm throttle body
-C&L plenum
it's a auto btw

you should have had them redo the graph.. you should complain about that mess. Your numbers look normal and especially good for an auto. Untill you get a headswap or PI intake you may not get over 200rwhp.. but your torque numbers look great for what you have.. better than most 99+'s out there.

SR 97 GT:

My numbers (in sig) are close to yours (and our mods are similar). I picked up about 5 hp with the tune but, more importantly, fixed a lean condition.

**edit-- Well, I haven't updated this sig yet: 194.6 rwhp / 261.7 rwtq. Pardon the error! ** end of edit.

What's it supposed to look like?
I know they had a problem with the overdrive engaging. That would probably explain the huge spike.

The pre 99 GT's didnt have but about 210 flywheel hp to begin with. Reduce about 13-15 percent of this to for an approx. number of rwhp in a five speed. Make it 16 -18 percent less for the auto. Thus, a stock automatic would only have approx. 171-177rwhp. Comparing this to your dyno, you have about 15-20rwhp over stock.

Most of your power gain you have over stock is probably comming mostly from the exhuast mods and pullies. The intake mods arent going to do much for you since your cylinder heads, cams, and displacement are still stock. All together, Ide probably spot you about a 20, maybe 25 rwhp gain for all the mods you have. So, it doesnt sound too far off. Maybe if you did the dyno over again you might see a little higher numbers but I'de say 200rwhp would be the most you'de ever see considered its a 97 auto GT w/ only the mods in your sig.
