When Ian tuned it He was getting a lot of false knock readings and wasn't realy happy tricking the knock sensor so didn't.
He said there was no knock in the det cans butility didn't want to send a car out that couldn't look after itself.
I've since found out what I suspected to be the case that something was touching/rubbing somewhere and I was right it was my gredy oil pan on a undertray mounting point.
Ian has said he's happy to push it more if I like but see how it feels first
To be hounest it feels so much stronger it pulls like a bloody train now so think chasing numbers would be daft
I was told 400wheel was a nice safe number on the stock pistons with them being cast
Longevity is the key here I can't afford a rebuild lol
Colin at creative seems a good chap mate cheers for the contact
I'm going to pop back and see him at some point to discuss a few other bits
