JTS Top End Speed Lacking?? De-coking / ECU replace/remap?
I managed to test the top speed of my car (completely legally mind) and I found something strange.
At about 6000rpm in 4th gear it looses all its thunder. Pulls like a train to that point and then just seems to kinda get stuck there. It goes from pulling hard to then suddenly pulling very very slowly.
It is on a uphill stretch, but I have trouble believing that, that is how it should be.
Did the run with the MAF and without. Without it, it did pull a bit more eager (could have been my imagination too) but it still got to 6000rpm in 4th and same thing happened. its got another 1000rpm to go before I would change to 5th, I even did try changing to 5th and it gained nothing either way
It had its full 60k service done about a month ago.
It could be the injectors, with the JTS its possible, surely I would notice it in the other gears too? Yet in the other gears it feels spot on.
Air filter maybe? I haven't checked it but I would hope at the full 60k service done by the specialist that would have been done, I did ask for the pollen filter to be changed during that service too.
TBH it doesn't bother me that much because I can never do that kind of speed normally, but the fact my 1.6 civic could do the same speed leads me to believe something is amiss lol
