Got the Vectra booked into Falkland Performance to have hte Superchip fitted on Wednesday, not expecting massive differance but hopefully just a bit more pull. Full report once its done, then its off to star with the guys from Corsapsort on the 3rd for a rolling road day see what differance its made.
Yip it was up yesterday at the Scoobynet rolling road day. It did through up something odd though, when the car was first rolling roaded last year (November I think it was) it had just covered 1200miles and showed 185.5bhp and 206lb-ft, however it has since had a Magnex cat-back system and now has 4,500 miles on the clock and gave 168bhp and 190lb-ft, with near identical grpahs bar the drop off at the top which is very very slighly different. Fancy having it rolling roaded at AVA at some point to compare the readings (dont know if your maybe up for a fewof us getting together there and making an afternoon of it?)
Nae looking at the 2 readings I think the first 185.5 bhp reading is out and aint accurate. the 168 is accurate and near bang on for the car, whereas teh 185 really aint close. Looking at the 2 graphs as I said only the very top of the curve where power drops off is different the rest is identical. Once my scanners working again I'll post a pic of the 2see what they're like.
I had my car on three sets of rollers in about two weeks last year. All produced different results. So I no longer get too excited about rolling road results unless it's a rolling road day and then it allows comparison between similar engines.
