Since getting an old 911 as a second car, my Qubo MJ 75 has felt really slow and unwieldy, so I decided to do something about it. Stage 1: a re-map.
Took it Celtic Tuning today, and asked them to crank up the power. They tried several maps, and kept the one with the best power/torque balance - I could see what the dyno was showing on the flat screen in the waiting area. Now producing 102 bhp, and 169 lbft. I drove home the long way, with a couple of detours to get a good mix of driving.
Previously, there really was no point in revving past 3000rpm, as it felt quicker to change up and rely on the torque rather than power. Now, it's worth taking it up to 4000+.
Floor it at 70 in top, and it actually accelerates.
It'll pull top gear cleanly up hill below 40mph. On the original map, there was a nasty stutter just before the turbo came in.
I feel that it was £275 well spent.
My next task is to do something about the body roll. I'm thinking lowered progressive-rate springs. Problem is, I can't find anyone who lists uprated springs for the Qubo. Are they the same as the GP?
