It took about 2 hours of tuning to get the car back to where it was. I was not going to blame the header for losing power until the car was tuned.
Way to many people bank on a "tuned" ECU and just slapping on parts to make power. I can not stress how important it is to have these cars tuned. So many people are dissapointed with their numbers but, very few invest the time to have the cars tuned.
Many of the guys in FL including myself went to the track and trapped 100-101 mph with bolt on VE's with SR16 non N1 cams. I see many N1 cammed cars not hitting 100 mph. It's all in the tuning.
Props to the boys at Mazworx.
Dam Straight! Same with the cam gears, initial change from 0-0 we lost power but you could tell there was more power from the lean spots it created in the tune. 2hrs tuning and you're better off, cheapest mod ever $300 for 10wkw. but anyone with a epprom ecu and stock ecu will never be able to see this.

Just perfect this thing to the max of your abilities and don't rush it to the market just for sales please. The real buyers knows what goes into these headers and will not have a problem waiting.
