Must admit TDis quote of +15bhp on the HKS induction seems high, however I have tried the car with the HKS induction off and the car definatley is slower at 4500 rpm with a stock air box.
The mod that made the biggest difference was the de-cat : INSTANT surge of power
I have driven an auto TT and of course they are faster than an NA.
But a manual NA will keep up at low gear do to its different gearing to around 60mph, then the TT will fly past
No matter how you drive and what buttons you press, a manual gearbox is more controllable than an auto.
Thats why a 94 model manual 6 speed TT will sell for £13,000 compared to £8,000 for an 94 TT auto.
