After comfortable with how things look stock, either pick another map on jb4 or reload bm3 map, and log again. My racechip results were similar to yours....at couple thousand da did 10.8-10.9 at 129mph. |

The trap is OK but the ET seems pretty slow, most JB4 cars are doing 10.5s or better, best I've seen is 10.0s. Same for flashed cars. Might be something wrong there.

I am going back to stock, will take it in to dealer to check for any boost leaks, check fuel pump efficiency.
Car has new air filter, spark plugs and tires. No cel but slow compared to every other car on the forum. |

More than likely it's gas related bud. U need to be at 93 or better 95 for good results. Can U list ur mods here?

What is a safe mixture for regular gas and E85 without having a proper e85 kit?

Impressive. Does the BM3 have a top speed delimiter? I thought these cars have ignition cuts at around 158mph.

I don't have an e85 kit. U can start small like 2 gals e85 with rest fill up off best octane available and build from that. But I wouldn't go more than 7. For most people sweet spot is 4-5 gallons.

Do any of the piggy backs take care of the check engine light caused by primary cat deletes? Or is that flash only?

ur DA is extremely high and you are running an OTS Map which is more conservative usually. I have a 2018 Non comp with bootmod3 stage 2 AGG tune (OTS) with a full turbo back exhaust. I recently did 10.6 with similar DA as yours. only thing is my tyres were completely destroyed and am expecting better timing with brand new PS4s

You can datalog your car for now, JB4 won't do much on the newer software anyways and with JB4 you will leave high than stock values in the data without being able to clear it as you can with Bootmod3.
