I have just bought a new ported and polished head for my s2. It has come with a newman cam and solid lifters not sure if it has bigger valves or any other work but is all going to be fit to the car this week. The car also has Pro Alloy Front mounted intercooler, chip, exhaust and filter. Im going to take it to a tuner to have it setup and want it running somewhere around 18psi. Is this a bit much for MFI and a standard T3 turbo

Thanks
