Honestly before u guys get all pissy ive read and read and little more reading. My car bucks and jerks and bounces so so so BAD at part throttle. Most all the threads i looked at seem at wot or when starting. Mine is in any gear crusing on the freeway, neighborhood, normal roads anytime im bareky on the gas i feel like my car can hop a fence lol. The only way i can drive is give it gas, then let go then give it gas etc if i hold throttle at a single spot thats where the problem is. Where in ecu flash can i fix this issue thanks

 

Have you looked into COP sorry about that. my 8 used to buck in 1st a lot and that is what I was told would help fix that issue. But reading you post more I dunno if that's the problem but mate it couldn't hurt

 

I currently have a spoolinup cop. That really didnt make my car feel any diffrent

 

Damn man I'm Sorry to hear I wish I could be more help good luck man I hope someone can help you out

 

There could be a myriad of issues your car has. Tune, ignition, plugs.

Your car, you can hate it if you want but no one here can help you without a little history. There are plenty of people with various amounts of horsepower that have no issues.

Do you care to elaborate?

 

Yes me too its a pos! Ha thanks anyway man

 

How'd you get to this point? What mods? Who tuned it before? What have you done so far to try and fix?

 

Sure my car has new bpr8eix plugs gapped at 20, spoolin up cop. The tune was done at a local shop. The injectors are fic 1650's pushing 32 psi on e85

 

Also has vta bov but tuned on SD

 

try the oem bov

 

The oem wont hold up to my 32 psi. I really thought speed density was sposed to fix this issue

 

What blow off valve do you have? If Tial, then what spring is in it?

 

Talk to your tuner...he should be able to figure it out. Mine turned out to be plugs, only drove on them for about 1k miles before they fouled.

 

Did you buy the injectors new or used? flow tested? Its possible one or more of them is not working properly....if possible swap them out with a known working set and see if it helps...

 

Can try throttle body shaft seals. My car does this too. I ordered a set but haven't installed them yet or I'd let you know if it fixed the problem
