[QUOTE="Fastphil, post: 12490041, member: 39941"] I put the Cobra away for the winter last week. It's time to evaluate what needs to be done in the off-season. The big news is that I just ordered Accuair's iLevel controller. I'm hoping to have it under the Christmas tree because it's a partial gift from my girlfriend. Every guy dreams that his girlfriend would buy him something really cool for his car, and now I'm one of those guys whose dream will come true. :) Of course there's no hurry to get my hands on it because the car is stored off-site and I won't be able to install it until the spring anyway. In the meantime I'll get informed about what iPhone I want to buy. Surely an iPhone 5. Since around the time I took my car to Billet Pro Shop and had it up on the lift, I've been having problems with the ride height on the rear suspension. When set on preset 2, it airs out completely regardless of whether it is at the right height or not. I'm thinking one or both of the sensors may have suffered some damage from being on the lift. I am NOT blaming Billet Pro Shop for this. In the spring I will swap the rear height sensors to the front of the car and the fronts to the rear and see what happens. If the rear still airs out, then I guess the problem is inside the ECU. I tried redoing the automatic ride height programming and setting the height presets manually, but that didn't help. I'm hoping that Accuair will be able to help me out in resolving this problem. I don't care to spend $500 for a new ECU if this one is on the fritz. I'm also mulling over a couple of other possible projects that will require investing a fair sum of money into the car. Not sure I want to proceed on either one at the moment, but if the mood strikes me, I may pull the trigger. First is a possible upgrade to either one or two Air Zenith OB2 compressors from my current dual Viair 400C's. This doesn't require a whole lot of preparation, but those OB2's are quite pricey. I may also bump my system up from the current 150 psi to 200 psi when I make the switch. The next project is not suspension related, but a comprehensive power upgrade which would net me another 40-60 rwhp. I'm looking into supporting modifications at the moment which would be required for a blower upgrade. Not so much a blower upgrade, but having the stock blower ported.
