I know this has prob been asked before but has anyone driven both these conversions. I have a MY03 STI ppp and fancied the WRC 350 upgrade mainly as it makes use of the PPP stuff already fitted hence cheaper. Prob seems that as in PPP cars the figures quoted for BHP/Torque seem to differ wildly on real life cars.

 

Or does anyone have another comparison of the WRC350 vs ..... (similar priced) upgrade

 

You can still have the TSL 333 remap using the existing ppp bits. Mine retains the prodrive exhaust etc. In terms of figures on the rolling road produced 332 bhp but torque was way down @ 295. Looked at the WRC packages as I am a bit disappointed with the the car in its current guise if I'm honest but took some advice off AndyF and have decided to go down the new turbo and exhaust route with remap. Should see me with 360-380 bhp with similar torque. Budgeted £2k.

Looking at WRC they wanted a bit more cash to get to these figures. Having used Andy in the past though my mind was made up!

Might be an option for you mate?
