Default Crank

wheel HP numbers for a chipped 1.8T would be between 150hp and 170hp

Default

Crank, assume all hp figures are crank unless noted otherwise.

Default so the X-chip provides much smaller gains than an '01 APR chip? ...

or are these figures not for the X-chip, since it says 91 octane? I'm lost. I thought the X-chip puts out more and we even had dyno plots to prove it (including yours from AWE).

Default no.. the gain is relative so it should be the same for wheels & crank

afaik on '01 x-chip has most power/torque increase over other chips but not as smooth as apr

Default I highly doubt that those are for the X. Crank HP on my car came to 217hp which was derived from

169 power to the wheels.

Default none of those part numbers match the X chip...

Euro cars probably have different chips, etc...

Didn't you bring your car with you?

Default

yeah... mine is a US-spec, and I have the X-chip, I'm just puzzled by these numbers on GIAC's page.

Default Yeah, they don't make much sense.

For all comparitive purposes it would be fair to say that your car is making 170 whp, and approximately 215 crank.

My numbers were identical to the two other X chipped cars that ran that day, and almost identical to silver surphers X chip dyno (he had made more torque however).

I don't know what the differences may be considering you use European gas.

Default I think the APR CH chip and the X chip are about even. Difference I've seen on dynos could be

attributed to individual car variences. The only head to head dyno I've seen had the APR making ~2hp more than the X chip but the X chip making ~5 (??) ft lbs more torque.
