notable improvement in power

Reviewed by yianni e. (Penshurst, Australia), reviewed for EVO-Tech Performance Chip for Ford Sierra - Sapphire 2.3L – Sunday, 1:51 AM

Postage was fast and I am not computer savvy still coped with instaltion in fair amount of time. Unfortnately there is no preset tune thus you have to dial the tune for a good while, until spotting on the best settings that maxes out the performance not being a placebo like after the first turns on the knob. Support is conscientious but no phone calls accepted and no callback. The product delivered notable improvement in power and at my astonishment it also lowered my fuel consumption. Overall a good product.
