Cpl are offering a package of ecu, chip and conversion harness for £629

That's the one. Think it's £550 w/o the harness, I bought mine from boomslang, was about £20 cheaper and quality is pretty good

its so true though

30 seconds of epicness and 6 months of annoying creams and pills

This is a confusing thread.

It will be an OEM S-Spec engine at 217bhp.
So
- Your AEM V2 or ideally the better OEM Type S dymanic intake.

- ATR Intake Manifold portmatched to a 68mm TB.
- S300 with remap as you have no ATTS to keep you happy so OBD1 will be fine.
- Custome Exhaust Manifold to a 2.5"+ exhaust like a Hytech, replica hytech or custom Tri Y from Solid fab etc.

That should see you net around 240-250bhp going off the figures people run with the above setup on an A8/JDM redtop engine.

Pretty sure 68 is the safe limit really. I recall reading that on here somewhere!
