I have been fighting what I thought was cat overtemp in the summer. Or running the car in really hot weather for the first time. I was having issues with
the car has been falling on it's face and picking up again during a pass. The injectors were working hard and it was adding timing.
As the weather cooled and the car made more boost it was more noticeable. You could see the car lose power if you watched it go down the track. I had a video of the dash guages having crazy rich afr and boost would go from 12-8psi, then back up and down again.
We logged it yesterday with hptuners and saw the fuel pump pressure below commanded pressure and the injectors went past maxed out so the car blead boost to save itself.
A fuel pump change will be happening this week and I will be checking it at the track on the weekend.

Synopsis of the weekend :
This is a car I can drive anywhere any time. This weekend the got the usual race prep .
Remove passengers seat , install viper drivers seat and bolt on 4 wheels and tires . That's it for my race prep . The only other thing for this weekend I tried my flex fuel tune for the first time at the track .
This is basically a demon / redeye engine with a 10% OD lower pulley ...that's it . No chillers , no ice box , no 15 in conversation, no aftermarket superchargers . It's a pretty simple set up . I used as many factory parts as I could . Some of them are from a different model but they are still factory .
You have all heard me say " it's all the little things "
In my opinion the 2.7L IHI is a fantastic street supercharger when set up properly. You can't spin the bejesus out of them or expect miracles. After all it is a factory installed part .
I did find out this weekend the limitation of 1050X injectors so I will be addressing that with a set of 1300's for next year . I also ran into torque management issues from the new found power of the E85 but I figured them out and addressed them . Every time I fixed 1 issue a new one would pop up . But atleast I'm able to deal with them .
So for next season I will be doing the drop in rods and pistons and 1300 injectors and continuing my E85 adventure.
Man I love this car !
