I just got my 93 mustang tuned with my vortec supercharger and add a Anderson power pipe to it and now it's idling alot higher. Do I just need to retard the timing or get a new tune?

Everett

Get a new tune. You will be flowing more air now and you need the tune to compensate with more fuel. You don't want it to lean out

darkhorse93

If I put the stock setup back on should it be fine again?

darkhorse93

Well I put the stock setup back on and the car is idling hard and running rich. Any advice?

Everett

Ya. New tune. You changed the flow characteristics and the cars computer cannot compensate enough.

Great just in time for the track this weekend

Everett

****. Well I hope you work the bugs out so you can enjoy the weekend

What if I was to buy a pms kit from Anderson power sports? Is that worth it?

Everett

I cannot answer that one from experience. Sorry

darkhorse93

What size throttle body and mafs should I be using? I have 65mm for both

If you have a intake cam heads etc...that's too small...at least a 70-75mm...do ALL THIS. Before you re-tune the car. And as far as the anderson pms im getting one in the next week or two also...never had/used one but heard they are great! Put that on as well before the tune... gives the tuners a advantage I hear. Good luck lemme know how it works out

darkhorse93

Sounds good. Thanks for the help

darkhorse93

I should have my anderson pms kit in the next couple days. I will be looking forward to tuning the car

The pms kit came today! Can't wait to get started on it
