Turbo LSx breaking up in boost
Turbo LSx breaking up in boost I will try and make this as short as possible.
370" LSX turbo th400. Car has been strong since it was tuned back in may. Took car to track 2 weeks ago ran 9.80@150 no problems except traction
Took car to chassis shop to have some tabs welded for tie downs and some mounts for the new afcos
take car back home and park it. its been about 2 weeks since last ran in boost. I take it out on the wastegate spring ~5lbs and it breaks up real bad in the boost and with 65-80% throttle out of boost. I checked plugs and went ahead and threw in a new set gapped the same.
No faults. Car is e85...wideband scaled for gas and when breaking up it shows 13.2-14.0
Waterman mechanical pump with good pressure. Tested fuel still 90% e85. Put a timing light on each wire and it shows spark. Pulled valve covers and everything looks good. Car maybe has 200 miles and about 10-12 passes. all new parts. Car is SD Tune.
Narrowbands when logged are all over the place. Probably alot of info but if anyone has ideas please let me know. Proly going to take car to tuner to have another set of eyes on the numbers to see whats up.
car ran so strong and nothing led onto this happening at all....its gotta be something simple just not sure what
