I wouldn't say that the number of runs etc or difference in temperatures would have caused an effect here as this is all measured with a dyno dynamics and taken into consideration when your HP is worked out.
I didn't really go for numbers, if I did I would most likely have gone to PHQ but let's not get in to that. I went to see what an AFPR could do, a learning exercise for me for afrs, maps and fuelling and to prove to myself that the engine is safe and in good condition (which I sometimes wondered when revving the shit outta it) which the read outs showed.
David, thanks man. You are probably right. I think the car probably is running better now than it ever has. It certainly feels it.
Anyway. Replaced the passenger bottom arm today and BINGO it now drives straight and the wheel sits nicely where it should. Looks like this should have been done as many as 4 years ago. It had a 4-5mm bend at the end of the arm where the ball joint is which is odd cos I'm not sure how that damage could be caused...regardless, it was a £40 part.
You know, I'm really not sure this car has been looked after at all other than regular oil changes and decent mods.
