Dyno tune is done on 93, The tuner feels something is holding it back On how the hot pipes meet with the turbo. Tune was done on 14 lbs and not changed. He did say its not coming into full boost till 5200-5500 RPM

Everything i have seen on the web looks like 750-850 was in reason, We only made 627.1. This project is not done and im in search of how to get more out of it.


What do you guys think?

 

750-850 was a pipe dream

Number seems pretty expected based on mods

 

Low timing ?

Given mods and combo on shitty Dyno that's on par

 

He tried every thing with timing, said motors runs great just not making any more power. He even started to pull fuel and it made less power, said it likes more fuel

I have dual 450's in the tank and plan is to change to E85 for more boost later this summer.

Is that a shity dyno?

 

It's a dyno number. In isolation it means nothing. Just use this as a baseline for future changes.

 

Curious what was best power fuel and best power timing

 

I hear you, Its been a long road and just want to enjoy it this summer. Thanks guys

 

Big mud 33 in tires kill power. What was the timing? And 14lb of boost on 8.9.1 cr isn't a lot of boost.

 

He emailed me the tune, He used my V2 to do the tune so is there any way I can look into it to figure that out? I didnt ask him any of these questions.

 

33s aren't much larger then stock , my 35s were only 10up different
