please reply so if i have the fac. shaker my perf. tunes arent correct?

if i add any thing such as better under pulleys will i need a custom tn? #2 if iadd turbo- or super crger certainly i would have to go custom. what does standard air box mean that reads when i'm changing my performance tune? i have factory shaker borla h-s-- cold air intake. my tunes have taken well...

i noticed i have a on performance etc. 93 oct. applys to i think it says stock air box?????!!!! i have a factory shacker breather!
should i go ahead and get a custom tune ---
plus im pretty sure i'll need a custom tune if i add a super charger1

okay 4th try you guys have figured that i have 320 rwhp what does that equate to on fly wheel horse power =some-one ask me hey how much hp u running? well i'm not going to answer 320 rwhp= in laymen/commoner terms the answer is real hp=fly wheel. if im at 370hp i would prefer to say 370 not 320 np t...

thanks'
means i have work to do in order to reach 450 horses!

hey , cool u got a stang! i'm trying to figure flywheel or real hp = engine hp, so when my bubs ask i can give plan hp the one laymen=commoners use = not wheel-- im looking for some type of formula for converting rwhp to rhp.
thanks
please e-mail me back

okay 'we've narrowed it down after 3 tries-- about i ask about- what does 300- rear/ wheel/ horse/ power =equate to -fly/-wheel/ horse /power???!!!
thanks

p.s. hp

so 300 rwhp=340 hp

i'm still new but not going away until i get the most out of my tuner! i still believe some one out there has a formula to calculate --rwhp-to rhp! i'm not looking for a dyno! just ballpark. 20 whp =hp.? example when my o6 gt pony came out i was told it carried 303 horses.i don't think the dealer me...

:? please i just put 91 oct tune on my 06 gt pony--i can tell some differantance i think i was expecting more/ my cobra friend said i probally picked up 20? is this 20 rwhp --or rhp no one know-- i just figured that there has been plenlty of study by diadlo on hp for each make! i have factory shake...
