May Need to add some rear steer. I had the same exact problem when I added the blower to my 248 Undercover dragster and started turning up the power, it was always hunting to the left going down the track from 60 ft on. Don't remember the exact amount I added but it cured my problem. If it is going left then you would shorten the bars on the right, exact same amount on top and bottom. It sounded backward to be until Kurt Damron explained it
You results may vary

Thanks

just a thought have you measured the tires

Yes I have. Goes straight on motor but goes left when spraying

things like that tend to escalate as more power is added,stev may be on the right track.

I mis spoke when I said to move the top and bottom bar. Neutral the top bar if you have any preload in it. Remove the bolt from the front of the bar. Then loosen and shorten the bottom bar, my son thinks it was 1/8 to 3/16 max. Then re attach the top bar and reset your preload if you have any. When I got really fast I actually had like 1 flat negative preload

Pretty sure Tim McAmis has a video on rear steer.
