That makes sense and would explain the change in performance I noticed.

I was disappointed that he didn't do a test run before we made the changes so we would have a baseline to compare it to. He did have concerns about the pump, so we switched it with one he had, but that was before we did the dyno runs. He said he refilled the coolant but the next day I checked it...

It was the upper snout pulley changed to a 2.55in. Smooth Flow. I was there when he did the dyno pulls and I took pictures of the computer screen after each run, here are the numbers, Run #1 Max Power 373.21 at engine RPM = 5.74 Max Torque 382.80 at engine RPM =3.94 Run #2 Max Power 381.38 at...

The name of the shop is SpeedLine Performance, in Ocala Florida and the owner is Michael Carpenter, he does the tuning. He said he does not have a tune for your specific car but could tune it similar to the way he did mine, that was making changes after each dyno run, there were 3 runs. I'm not...

Yes, I can do that, I'll try to contact him tomorrow.

I had my 2007 V dyno tuned last year, the tech told me he was using HP tuner software. I don't believe HP had a "tune" for my car, the tech said he made his own tune. Take that for what it's worth, I don't know the guy personally, but I have no reason to doubt him. He is the owner of a local...

There are only the two battery cables on my 2007 V, no additional wires. I agree with Mickeytee, you should at least be getting some lights so check your cable connections at both ends.

Not sure if I can help but I have a few questions. Did the top go up and down before you changed the lift cylinders? Did you change the cylinders or did someone else? If it worked before, then something you did, on purpose or by accident may have caused the problem, unless something else failed...

That's my concern also, if I spend that kind of money, I want to be able to use it on different vehicles. I'm looking at an Xtool, D7, I don't know anyone that has one but I have read some good reviews.

Thanks for the info on the VCX, I had changed my mind on that one and I'm still researching different units.

UPDATE After replacing the solenoid actuators I have noticed a dramatic increase in low end power. I don't race the car but I do like to get on it once in a while if I'm on an empty country road. Since I changed the actuators it overpowers the traction control and gets exciting real quick. In...

If I had to guess, I would say no but that's only a guess. I swapped a bad cd changer out of my 2007 XLR V with a brand new one that was made for a 2006 Cadillac SRX, it did work but I had to install the mother board from the old unit to get the steering wheel controls to work. The point I'm...

You're welcome. Job well done.

Glad to hear it, good luck moving forward.

Good for you, I had the same airbag warning light, and it turned out to be broken wire under the driver's seat. It was an easy fix once I figured out what the problem was.

Thanks for the explanation.

Thanks for the reply, I have no experience with VVT so I wasn't sure. I was trying to figure out what the magnet did to change the operation of the valves but I've decided there are some things I just don't need to know. No leaks and it's running good, I'm a happy guy.
