Doubt I'll be getting it on the dyno anytime soon. I did mash the peddle this evening on my way home. Roads were a little greasy, had the wheels spinning in first, second & a little in third. Wow, for a hearse this thing really gets going once you get the power down. Pleasantly surprised. Hoping to get a further few mods added over the coming weeks.
On a side note I tried getting the JB1 discounted to no avail from JB4Shop. If anything I wouldn't be surprised if prices increased slightly. I believe they are reasonably priced already for the kit you're getting. The customer service from JB4Shop was good too.
However I opted with NV Motorsports in the end as they were competitively priced (£375) & fairly local to me. The chap I dealt with Mabz, who has a crazy Cupra
280 himself, was really helpful & seemed to have a wealth of experience particularly with the MQB platform. They also had a few JB1's in stock with Map 6 set up specifically for the Cupra
280/
290's. I opted for the JB1 rev2 (no custom Cupra map) as it has the option to upgrade to JB4 in the future. But on second thoughts, maybe I should have gotten the JB1 preloaded with the Cupra map. Either way I'm fairly chuffed based on initial impressions.
