Short answer no. But it would be recommended ( or atleast a nistune )

Not if you are being conservative/sensible. The stock ecu will support more boost, especially with 98 octane. Done on a dyno to ensure sufficient fuel mixture. I do Nistune for milder applications, bigger injectors, larger MAF and big numbers are still acheivable with Nistune, I lean towards aftermarket fo big modifications though. I tune a number of 9 and 10 second VL's and they all use aftermarket ECU's
