no change in mods.. that dyno that was done today is no tune..we were getting a baseline for when we dyno tomorrow with headers and berks HFC..we are getting true numbers on if the headers and hfc make power over stock headers

Cool! I really hope you get your goal of +20 WHP tomorrow. best of luck.

sweet ready for updates

Parts just arrived Seb is working on it now will update in a few hours with some numbers

Here are the results 307whp and 237 wtq no tune

Nice so far!! Mind I ask how long was the install for the shorties?

Would you mind posting some of the graphs for comparison. Id love to see where the powers being made and if there's any lose in the lower rpm band.

I'll have Seb email me the files when we are done most of the power was all top end
It took Seb 4 hours to install them

When is the ecutek tuning coming

I'll post dynos tonight when I get back home.. But I can tell you the switch to ECUTEK is worth it.. The throttle response is 100 times better than uprev

I gained through out the entire power band with ECUTEK but only 3 on the top end so 310whp

291 to 310...not bad at all.

Are the collectors 2.5" when mating to the cat or TP?

Not bad not bad....looking forward to the dyno plot... I may skip headers and do art pipes

here it is
Red is stock header Gen3 Berk HFC Ark Ported Plenum 4.08 gears no tune
Blue is Z1 Headers Gen3 Berk HFC Ark Ported Plenum 4.08 gears no tune
Green is ECUTEK tune Z1 headers Gen3 Berk HFC Ark Ported Plenum 4.08 gears
