Hey guys! As of the 23rd I am now Jestr Tuned. I have to say that Jestr is a genuis when it comes to tuning the 4g63. What he did to my car was unbeliveable. I also would like to thank Scott from TTP for a great install of the cams and studs. I think there was more power on the last run as i saw it go to 335 hp @ 7500 but Rolo stopped recording at 6500. Thanks to Rolo at CFT for letting Jestr and I go over the 1 hour limit. Next mods will be cam gears, 10.5, and intercooler. Once agian thanks to everybody that worked on the car.

That tuning looks great. Instead of a high torque spike to give you a false peak torque rating, you have a beautiful, smooth, and flat torque curve that tapers only slightly after 5500rpm.

That looks like some serious power, because 327 on a mustang is 350-360 on a Dynojet, and since I only pulled 282 on a Dynojet in lesser heat (I presume), then you're looking at some big-time power for the 9.8 hotside.

 

yeah Jestr told me that my car is a freak car and that this is the stongest one he has tuned for the mods i have

jeff

 

im strongly considering these guys it is good to actually get some feed back

 

Do you have contact info for Jestr? I was looking at your graphs again and i think im convinced. nice pulls man.

 

Yah, well now all you have to do is go run high 11s at 115-116 on pump gas to ensure the dyno's accuracy...

 

yeah i have his e-mail jestr@jestrtuning.com. jestr is a really cool guy i would give him a call if i were you and tell him jeff sent you.

Thanks man

 

Congrats Jeff. That car is strong. Both John and I were very surprised to see your numbers. The dyno is well known for it's rock solid accuracy. That last run too did not have a very long cooldown period and it had been on the dyno for about an hour and a half at that point. I have seen 272/272 cars put down less power than yours. That car should run very well. Let me know when you'd like to get those gears in and degreed. If you find a track down south, let me know what is does.

 

John is awesome. He has done quite a few Evos here in Orlando and they all have had great results I would recomend him to anyone here and you wont be dissapointed and its worth the money.

 

yeah i am going to be getting another flash come september(3 pay period) so i am going to have cam gears and everything else then.

I have a silly question what is the difference between a mustang and a dynojet dyno?

 

Do a quick search, and you'll get the detailed answer. The short answer is that Mustangs read much lower than Dynojets on average...

 

looks great.

what dyno does he use?

 

he uses dyno jet or mustang dyno it is which ever one the tuning is being done at.
