My 4/4 Sport was tuned by Cain. It its now at 132bhp (from factory 110bhp) only upgrading the exhaust manifold, silencer, K&N air filter and Wolf remap. It feels quicker than it actually is and drives really well with no idling or other problems.
Next step is Piper Ultimate Road cams (requiring head work) and a new Link ECU (they are fitted to the race cars Cain prepares).
Cain knows his stuff IME.
