Here is the Spectra induction system installed on my V and the corresponding dyno results. I picked up 32 RWHP and over 20 ftlb of torque thruout.

Throttle responce is crisper and the supercharger whine is noticable in full throttle operation.

$500.00 for the dyno time, software license and Brian Turner's expertise. He had a starting place with another XLR-V and did not have to re-invent anything. We did this all last Saturday.

Here's my sheet. They have no idea where all the Hp came from, but called it wicked on the road, but I already knew that. They had to change the shift points when they got done because it fell on it's face and then shot up like a cannon. When we where done it shifted like a B & M Hydro. Waiting for warm weather to take Wicked to Fontana Drag strip with D3 Design to get some numbers and see if they can get more out of it.

Very nice. The HPtuners website indicates that only the 07+ 4.6 liter XLR can be tuned. Is the computer different on the 04, 05, and 06 compared to 07+?
