You should have done the E85 with it. Let us know how it works out. E85 is the best mod I've done, plus the headers. My car is plenty loud with the stock NPP on sport/track

7Litre is right, several good Flex Fuel sensors out there and I'm using the DSX. Biggest pain in the *** is getting to the computer since its inside the front passenger fender where one wire needs to get installed in the ECU. Its worth the effort since you should see 20-25 rwhp gain and lower fuel costs also. You will get worse mileage but at a dollar less per gallon (approx in my area) it still out weighs the cost of 93 octane. I get about 29-30 at 80 mph on 93 and 22-24 on E85, however most service stations don't have full E85, most are E65 to 75. My area its normally about 70 percent. I picked up almost a 1/2 second and almost 4 mph in the 1/4 mile. Now with long tubes, xpipe and tuning my best pass is 11.009@125 w/1.56 60ft. Not bad for a few bolt one. phil@phdtuning has really helped me out with some additional tuning from where I was on my own tune.

The put the headers and x pipe on today. I guess they are tuning it tomorrow, but I'll get the car back Mon I think. Got my personalized plates today also, just in time :P
I also have an ECS supercharger on my car. I talked to the shop about E85. He said I should do meth. But, I could do both. Wonder if I could beat that 11.009 in the 1/4 ?

I didn't mention I had a supercharger. As far as I know, you don't need any fuel mods for E85. That's only if you have a Supercharger with positive displacement. Even with my supercharger, I don't think you need any fuel mods unless your going nuts with the psi. My headers are 2" , the tuner said to go with that because of the supercharger. Less back pressure.

Less back pressure does lower your boost for sure. You may still need additional fuel to run E, the lower the E content the least issues you'll have with fueling. E burns a lot more fuel then 93 octane. Even if you could run E40 or E50 your better off the 93 octane. It will still make more power.

They are about 4400 lbs and mine weighs 3395 with my fat *** in it. My 448 rwhp to his 600 rwhp. I think I'm good and lots cheaper for me then him.
