Well, you can still buy economy plates on eBay for $165 delivered, but you will have to have your tune modified. Brenspeed sells the billet plates for more, but they come with a tune revision as long as they have a tune on file for you.
Did you get a dyno before and after with the DRs?
Thanks,
JD

Unfortunately i did not. I asked about getting one only to see if it would be beneficial for a better tune and he said not really so that was my reasoning for not getting a dyno. I may have to order some deletes some time soon

It felt like "surge" of power right at 2200rpm, I also noticed that it stretched out 3rd a little longer. With the Vortech though it's much more smoother.
Great DIY mod if you can still find them on Ebay for $150..

I have had them for a few months now and you can see my mods below. Driveability is great, no problems and the tune was perfect when I left Brenspeed, but they have written me a new tune to accomodate the 110 mm JLT I added later. I tried the off road H pipe and it was loud and trumpeted bad. I put midpipe resonators in and it still trumpeted too much so I put the stock H back in and all is well, maybe a little too quiet but better than the trumpeting. She pulls hard to redline, with the 410 gears...first don't last long. I get 20-22 mixed driving and as much as 26 on the highway. My on-board computer always give me an average that is less than hand calculated, but I always hand calculate anyway. If you beat on it hard, hard , hard it will drop the mileage. I am glad I did it and I love watching the shaker hood....SHAKE.

Anyone out there with the Detroit Rockers that doesn't have 4.10 gears? I have 3.55s and would rather not have to change them out but also don't want to do a half-***Ed job and not be happy. I don't track the car and it's a daily driver...what do you guys think?
