I have no experience with them.

Only so you can say danger to manifold.

patsmx5 01-16-2018 08:15 PM

Those won't raise boost, so no don't run them, the weight will just slow you down.

Particularly when you factor in the sudden release of fuel and harder g force in drag race conditions.

Is this special for nitrous use or recommended for every car over 400 whp?

More like over 500+. I have tested to 450 and it was not a problem.

I was about to question his statement, but I think in that power range it's probably close enough to agree

I have done my reaserch today while at work and iam going to buy a nitrous express progressive controller with the touch screen it has all the features i want.

i also spoke to my auto builder today he sounded confident the auto will be fine.https://cimg2.ibsrv.net/gimg/www.mia...9dd2f07fa2.jpg

I do regret my ecu choice but its not really cost effective to change ecu and start tuning again.

nitrodann 01-17-2018 10:08 AM

Ah.. PS1k right?

Sorry mate, wasnt trying to have a dig.

mx5psi 01-17-2018 03:43 PM

All good it wasn't ment to get this out of hand my original goal was 250 and manual.

its a AEM EM4 its been a good ecu so far it does have a nitrous tab but doesnt have the features i want
