But you shouldnt really expect more from a special CAI. I mean, they can sell you on it all they like, but end of the day the difference between lets say a VCM and a ORRSM is a bees dick and is not measurable by anyone in the car. I got my VCM intake not because people say its the best, but because I felt it looked the neatest in the engine bay. I couldve gone for any number of different OTRs for less and got the same result. Im fairly sure APS is doing the Carbon Fibre VCM ones now, they cost a premium. Would you expect it to perform better than the standard? I wouldnt because I know it just looks pretty. But would average joe know that? Probably not and I think thats whats happened here. Theyre pushing a product, it may not be inferior in anyway but the way theyve sold it its appeared better than it is.
Ill be honest, yes the number does look poor. Being on E85 you would expect a little more. But we have to remember hes slapped a second hand HSV exhaust on and some oversized headers. I wouldnt be expecting the world. Couple that with a very conservative dyno and that explains your numbers. I would be shocked if he didnt get 260-265 on another dyno with a better exhaust.
As far as driving it goes, well we can only go by what he has said. Mine was certainly punchier all throughout the rev range but I did notice it a lot higher up. I noticed the auto was much sharper as well as the blip on downshift in sports mode. Now if he has an issue with how it drives, they need to be addressed with the tuner, its that simple. I personally got into my car after it was tuned and went huh is that it? Becuase when i did my LS1 the car was a complete animal off the line. But, different exhaust set up. But when I felt the car making power where it was tuned to, it was wow.
What I am afraid will happen is, old mate will walk in and will mention dyno figures and other workshops packages and APS will roll their eyes. What OP needs to do is walk in nice and calmly and say ok the engine light is on, fix that. Also, I have some concerns with the auto, its to harsh, can we have a seperate profile for normal driving and sport. Then it doesnt have the same pickup off the line as I was expecting, can we adjust anything? Walking in waving around a dyno sheet is a quick way for them to just strap the car loose and just do whatever will shut you the #### up, without actually fixing any issues.
