Arrington 90mm throttle body + Vortech without a custom tune

It's a new way to cruise control Lol

it's completely tune related, hemi's are speed density tuned and you need re-tuning easy fix from a tuner.

My car is doing the same thing I had a GSM supercharger on it and did not do that

now I have a 426 stroker no supercharger and it is doing the same thing with a custom tune if you fixed it can you tell me what you did to fix it

and i have the stock throttle body on it

Thanks Jim

@srt8jim: the issue is software based. the Arrington TB let's more air through even when closed compared to the stock TB. you need to get a custom tune.

The problem is the crappy 90mm tb. Those junks dont work and get even worse with compressors and turbos.

[xhikomarux]

well, you can only force so much air into an engine. that is weird though 0.o

[nosboostice]

so did you fix it and how.
