well guys for those of you that have been waiting, the tune is great. chris at efi logics did an awesome job with the tune. the car runs perfect and pulls really hard. it baselined 263rwhp and picked up 22hp with the tune. the final numbers are 285rwhp and 315rwtq. highly reccommend efi logics, did an awesome job. heres some vids

Dayum that dyno reads high!!! Ive never seen a bolt on gt in 28Xrwhp range before. And your car seems to do what mine does...it pulls til like 3500-3700 on the dyno and then it plateaus and then picks back up...its odd. Did you notice that when you did your pulls??? Listen to the first vid and then listen to mine...



It seems to pull to a certain point then just keep going and then pull again. I thought it was a slipping clutch for me but then i just noticed that your car did the same kinda thing. I thought it was odd.

Those are some pretty high numbers, good job

1999 GT

yea i noticed that too when i watched the video. and other bolt on gt's that he has tuned all made around 255-260rwhp minus long tubes. some others with the same bolt ons as mine and bbk long tubes made around 275 so i dont really think it reads high plus it is a mustang dyno which everyone says reads lower but is more accurate plus my buddys full bolt on gt without longtubes made 260rwhp on a superflow dyno lol
i wouldnt say it reads high...its all in the tune.......

Oh it reads high. Mustang dynos you are able to set the load on for better tuning purposes so they have more control on the numbers. My friend's full bolt-on GT with same mods as you put down 260rwhp and 279rwtq on a dynojet. My car put down 250rwhp on that same dynojet with mods listed in sig. But trust me, mustang dyno's are more inaccurate because they, more than any other dyno ive seen, can be tampered with to read the numbers you want it to read. They can read low, but they can read high as well.

thank you and like i said my buddys full bolt on gt without longtubes made 260rwhp on a superflow dyno..........every car is different not to mention conditions, tuning etc. not trying to argue but everyone on here bashes. im sharing me experience as asked by you guys, im telling you what the car made for power and the details. when i got my car dyno'd on a superflow dyno with just an off road x, everyone bashed me saying it read high and that mustang dyno's are the best. now i shared my experience and theres still arguing lol pick your poison. not bein a dick, just making my point.

take it to the track and see how accurate it is, dynos are very conditional, trust me i have been on a few different ones in the past few weeks.

1999 GT

agreed.

Just pointing out a common fact for you to take note of, incase your outcome at the track would not be exactly what your numbers foreshadowed. No harm, no foul. At least you put your point across in a civil manor. lol
