Mark@Abbey M/S 235 Report post Posted December 8, 2015 Been playing with NA cars still on our in house dyno, using HKS header with HFC fitted; Dyno plot below is the dyno plots of a stock car v HKS header/de-cat/exhaust system(no tune) and tuned with ECUTEK BLUE STOCK CAR GREEN BOLT ONS (HKS manifold with HFC/decat pipe/exhaust system) RED BOLT ONS + ECUTEK TUNE We hope the ACE header (manifold) with the 350 Collector will work even better when it arrives. 1 Keethos reacted to this Share this post Link to post Share on other sites
