Hi i have recently rebuilt my 4age ae82 twin cam engine with 4agze pistons. standard throttle body got the inlet whole port and polished along with the head and some lil mods to the butter flys that open and close. hks cams and gears not sure of specs have them written on the cam sheet gotta dig it out but I'm looking at getting it dynoed. can they change any think or over ride any setting in the computer to make it faster or any thing like that ect ? looking at fitting super charger in the future thats why i went with stronger pistons and all that sorta stuff.. please any info would be great cheers

With your current configuration, the only adjustability is in cam timing.

With the GZE pistons, I wouldnt thing you'll be pulling too much power as low comp isnt the way to go for N/A. Just wait till you get the SC on.
