As the title suggests, I paid a visit to Jamsport in Northampton at the weekend and have finally got around to reporting on the outcome.
I phoned Mark a week or so ago to ask if they could squeeze me in for a power run at any point and he suggested I tagged on the end of a mk3 Astra rolling road day on Saturday. I turned up and sure enough they had finished and got my car on the rollers. I said to Mark and Jamie that I was happy for them to make any tweeks if they thought it would help and Jamie proceeded to go into a full on mapping session! :D I hadn't pre-booked and Jamie gave up his time freely, top guy and I think somewhat addicted to perfection. I think they are very reasonably priced too!
Anyway, after mapping the DTA for quite some time they handed the car back with some pleasing figures, but more importantly a totally different car to drive. The mapping is so good now that it feels almost factory with a solid cold start, smooth idle and perfect part throttle manners. It's made a huge difference to my opinions of the ITB'd baby XE. :thumb:
Results:
155bhp @ 6866rpm
134lbft @ 5466rpm

Whats very interesting is the torque curve is very flat with around 110lbft at approximately 2.5k rpm.

For ref: x16xel with 4-2-1 manifold and system and Jenvey ITB's and DTA.
I am very happy with the car and more so with the excellent job done by Jamsport. :thumb:
