i took my auto 99 GT to the dyno today it has o/r H , magna packs 3:73 , UDPs , CIA , 70mm TP , shift kit and email tune from brenspeed ( no local sct tunners in my country )

first run i only made 209 / 240 and the car was rich , i was expecting way more but the guy in teh dyno said he never seen 99-04 auto mustang with boltons beats 230 hp

after tuning it a bet using only the hand held tuner and maximising the allowed timing in sct 4 which sucks to be only 4 i only made 218hp 252tq and there is still room for more timing to be added

the numbers were disappointing cus the car run pretty fast , i never got beaten by any 99-04 and also can take out any auto 05+ but manuals 05+ are very hard to take especially when not stock i also beat some stock or a bit moded LS1s and can hang with moded ones till the end of 2nd gear

here is teh dyno graph ( sorry for the bad quilty took with my phone camera )




i will wait for a new revision from brenspeed and hope to hit the dyno next week :)

huh my number were

231rwhp and 268rwtq

I have 4:10s, Mac O/R prochamber, SLP LM1, and JLT fenderwell intake, with a SCT tune(not dynoed)

I cant say I believe the beating modded LS1 and 05 5speeds. maybe a 05 auto.

LS1 with bolts ones i can beta from a start if racing a 02~06 capric or Luminas ( same as the new GTOs in USA ) but camaros ar hard to beat when slightly modded

yeah bro... you havent beat any ls1's. LOL. from a dig or roll. You MIGHT have got the jump on one at the red light but it couldnt have lasted more than a foot and a half.
