The best i got on my std car before it went into limp home mode was 530
we dont know why but it never did again on further visits to the same
rolling road.<br>
I then had a map from viezu and smaller pulley put on and it only made 575, the fueling was all over the place from 5500rpm <img src="http://www.jaguarforums.com/forum/images/smilies/frown.gif" border="0" title="Frown" alt="Frown" /><br>
I then had another map from gad tuning put on and it made 580 but again
fueling all over the place at the top end so it wasnt making power after
about 5500.<br>
Both companys reckon it was heat soak hence the car dumping fuel at the top end but i didnt believe that.<br>
I then got in touch with Stuart from Velocity, ordered their 200 cel cats and remap, they then put me in touch with
David Appleby (Aston Martin specialists in Banbury and now Velocity dealers).<br>Took it back to the same rolling road where it made 610bhp, the temp in the cell was 24c outside was 28c so the operator reckons on a cooler day it would make 620-630<img src="http://www.ftypeforums.co.uk/images/converted_files/smileys/smiley17.gif" border="0" alt="Tongue" title="Tongue" />, so basically ive made an extra
80-90 bhp <img src="http://www.jaguarforums.com/forum/images/smilies/smile.gif" border="0" title="Smile" alt="Smile" /><br>
All runs done on the same rolling road, so apart from heat everything was as accurate as can be.<br>
Oh and funnily enough on one of our hottest days of the year we didnt
get any heat soak, the car pulled all the way to the red line and
fueling was perfect.
