HELP strange power cut please HELP Hi to you I need your HELP PLEASE all i haven’t been writing over here because I was busy rebuilding my motor after i destroyed three pistons.
make a story short and the rebuilt is done , i took the car to the dyno and didn’t have one clean nor decent run tell know , my car is a corvette twin turbo LPE last i have made with it was 672WHP dyno jet with old set up.
PLEASE HELP ME , now i am in a big dilemma and i am lost , while the car is on the dyno and i am WOT to do a tune the car starts very smooth and accelerates great all the way up to about 4K RPM and some times 5K RPM and it cuts in a very strange way you can have a look at the video here under at the minute 1:01
You can see that something very strange happens and the check engine comes on for a moment and then disappears ??????????????????

I Dont think its the fuel pressuer we dynoed the car a 5-7 times and this problem happend 3 times maybe the AFR Is perfect I will try to post a graph today the car made over 650rwhp with 13-14psi with 12.1 - 12.2 AFR.
He changed the Wires before the dyno we thought about that and spark plugs are brand new.
Here is another vid I also have another I wil post it ASAP.
