LLoyd for the improvement you get there not worth it.

When i first had a twinky i had it a rolling road, then had the chip fitted and set up, it made 3bhp.
With a K7N, manifold and exhaust, FSE, and a head port and polish and cams it made 150bhp without a chip and with the chip 154bhp.

When i bolted the turbo technics on to it only then did it make a usefull difference as i was running 1 Bar boost with 10:1 Compression, i then got 220bhp and 250ft lb.

Superchips just not worth it, put the money into a manifold and exhaust system
