Hopefully nothing major but thought I would ask on here. My new ED30 which I found out looks like it has had a remap being stage 1 as no mods I can see scared me this morning when I floored it. Basically I was travelling at around 30 and then when got to national speed limit I floored the accelerator and the power did deliver after a second as was in Drive but also came a big thud with it which sound very scary.
Drove and accelerated fine for rest of journey to work but was a bit surprised by this big thud/jolt
