I just finished a full build with the d1x and it has a gt350 intake and TB. Dynod around 900rwhp on a Mustang Dyno however I found that out in the road driving in 3rd 4th and 5th gear if get on it from around 3k to 4K it misfires sometimes bad enough to throw a blinking check engine.
Oddly once it passes this range all is good and it takes off like a bat outta hell. The Fuel pressure looks good and it seems to run better at even higher boost so I’m not sure what’s up just looking for some ideas.
My tuner / builder said the gt350 TB was giving him fits yet on the dyno it seemed ok.
Any ideas ? Has anybody else used this TB on a boosted build and had issues ?
Clip attached. I’m a bit worried about detonation etc so I did it for only a short time, this was rolling into WOT.
At light throttle no issues fwiw and it runs on e85 w Fore triple pump / 1300 injectors.
