impreza wrx remap to 325bhp with original cat

Not many mods to be fair on this subaru impreza wrx 2004 as my customer bought this from someone stating that it was pretty original but having gone to surrey rolling road on one of Charlies power run days it was running dangerous fuel ratio and a remap was advised.

When it arrived for mapping yesterday it turned out that the car had a vf35, pink injectors, decat uppipe but still had the std cat downpipe and top mount intercooler. We were expecting it to reach 310bhp after i had remapped it but were pleasantly surprised with 325bhp :). This time no danger of lean running either.
