Here's my dyno when I believe I mixed in too much e85. Dyno operator let off early, and I ended the session. Added 2 gallons 91 and did some freeway runs that night; problem went away.

Best thing to do is to log the car and look at wastegate duty cycle, boost, trims, etc- and then tweak it from there. The JB4 should definitely help with PID control, although fine tuning the flash should help take care of those osscilations. Nice build and healthy numbers with our Stage II tune at 670wtq and 640whp on stock turbos.
If you bring the car by next week or so, schedule permitting, we can log it and see. Your plugs and coils should be just fine as we changed them when we did the Stage II tune, PCV, and chargepipes on your car last year - and they were gapped to .024. You might want to ask your new tuner if they suggest a tighter gap, but I don't think there is any spark blowout occuring here. |

So I'm now 3 weeks done with the install and haven't got to enjoy any power out of the set up. Getting crazy smoke when I gas it which is horrible I think. I flashed it back to the stock map and gonna go from there. Been waiting to get this solved but gotta keep setting appointments to go back and get the problems worked out. Still don't know what the issue or why's it's smoking so much. My cars been out of commission for almost 4 months, I can drive it chill on the daily but I haven't got to get on it and feel the power. I didn't think puttin the pure turbos on would barely give me more power than my stock turbos set up. But everyone keeps telling me I shoulda made way more power, well that's all I want!! "More power"

I'm telling you, go with a reputable local tuner who can log and adjust your tune on the fly, whether its on the dyno or street tuned. You're not running stage 1; seems like you want to push some limits a bit with e85 mix and the bigger turbos....your tune needs to be dead on, especially since you're mixing fuels.
I showed what happens when I mixed too much e85; I use to fill up at 1/4 tank (when light comes on), but now I run it down to less than 20 mile range, then fill\mix e85 so its a little more accurate. + the quality of e85 can differ from pump to pump. |

What to do?
So having this setup has been a nightmare for me. After that dyno run with all that smoke I took it to bpm and they said it is most likely my valve stem seals that are busted. Or it could also be oil bearings but they won't know until it's disassembled. I haven't even driven the car in months and I've never even got to enjoy all the upgrades.
Now my options are do the valve stem seals and pray that that was the problem. Or build the motor which is really expensive to do that on which I've almost given up on my car already. Any suggestions on what I should do? |

It seems like all the problems started since you installed the turbos. I would reinstall the old ones if you have them just to rule them out.

This. I would reinstall the old turbos if you have them. I experience a similar issue with white smoke on full throttle. One of my new plugs (not even a month old) was bad. They were all gapped at .020. I also ran a e85/93 mix. If you have the old turbos put them back in. However before you do check again all the plugs one cylinder at a time. You might get lucky .

We checked the car out - it has bad valve stem seals or an issue with the piston ring in cylinder 8. We scoped the turbos and from what we could see they looked ok. Plug in cylinder 8 was saturated in oil and all plugs showed signs of detonation. Cylinder 4 was misfiring but the plug looked ok. Perhaps too much heat in the combustion chamber of the rear cylinders caused something to go awry.
Will know more once it's torn down depending on what the customer wants to do. The current behavior indicates valve stem seals but the circumstance of it occurring all of a sudden on the dyno makes us think it may be a ring. |

lol wonder why he is selling it. from what I read op was all over the place using diff tuners. i counted 3 or 4. sticking w one is key but when trying to push the car to gain lots of hp takes a toll on the motor plus lots of money. hopefully op CSR isnt too badly messed up for some unexpected gus wanting to buy his dream car only to realize it will konk out on him soon after buying it. after all op went through w that car I wouldn't touch it
