Hey Hey.. I just finished the Street Fords DVD again and was wondering about the Splitfire DIY Preformance Supertune Service Kits. Has anyone used these kits the DVD shows a gain of about 12 to 15 rearwheel kilowatts.

What do these kits retail for seen an WRX for $299...

any info etc would be nice cheers geoff

you might get 12 to 15kw buy using that kit IF the old plugs, old leads and old air filter were rooted.

yer whs

15rwkw is a decent gain in hp close to 15% in our cars

not liekly with a ecu

so if the street fords test car's leads and plugs and alike were in average condition and then replaced with new items regardless of product would do the same thing? i might have to rewatch it lol
