K & N filter with the air silencer in place and a different set of mufflers to give it some noise. Nothing special...

Also, we only went to 6300 RPM on the dyno.

Great numbers! :thumbsup:


-Same here (silencer out) with the whole flowmaster catback.

-Same here, but with 1,200 miles, no fan and no battery disconnect for the muffler install, day before the dyno.

Numbers in sig.

We finally have a fully broken in car reporting stock numbers. I bet I've gained ten HP since I dyno'd (now at 3,500)...

Those are about right, you can see my mods are the same as yours, and our numbers are pretty close, only mine was at 1400 miles. After I put in royal purple motor and tranny oil next week I am going to dyno again (have 3000 miles). I'll post the results. Your A/F ratios are way better then mine. Mine dropped off the chart at around 5500 rpms. I need a pulley to get it to 12.

No battery disconnect or computer reset.

Thank you all for the good news. I wasn't sure where the car stood on power.

I removed the snorkel (silencer) and at 1670 miles I dyno'd my '03 on a Dyno-jet 248. 382 RWHP & 378.7 RWTQ.

I added a Magnaflow #15644 Cat-back and a UPR CAI: That resulted in the 411 RWHP & 388.6 RTWTQ where I am currently with the stock Intermediate Pipe.

That should give you some comparison numbers for now. I'll be adding a Magnaflow #15445 O/R Intermediate X-Pipe in the next two weeks. I'll get another dyno after that and again repost the latest numbers.
