Thread: Trying to decide Overkill or ZZP tuning

I'm trying to decide on tuning here which will be better for a 2003 N/A grand prix. future mods are power log, 3in dp, tb spacer, and tuning. just need input on which is going to be the best tuning for the buck. Thanks in advance

TB spacer...lol, skip that.

Buy a PCM from 3800Performance.

It's a DHP...done and done.

500 is my set spending limit so thats my simple recipe

Definitely headers not dp and all that

TB spacers are waste of money

His n/a so unless he wants to lose some low end torque a plog and downpipe is good enough for him.

How are spacers a waste of money? cool sound and a tiny bit more air every little bit helps IMHO. Still up in the air on tuning here?

I like my overkill tune

Have you ever tried any other tuning? If so how would rate them on a scale of 1-10

I purchased a Zzp PCM way back when I first got the car I was not a fan seemed to cause more knock then the stock PCM. Down the road added more mods and went the overkill route could not be any happier..it killed a lot of knock I was getting. The trans shift points were firmer. I rate it a 10 I will in the upcoming months will be making a drive to have a local adjust it for cam and getting my a/f were it needs to be instead of sending it back for a retune.

A few guys seem to have problems with Zzp tunes lately. Only downfall to overkill is it takes time to get in contact with him and since he's in Canada shipping takes time.

Ok one last Q is the 185* fan on offered by overkill like the competitors noticed it doesn't say any where on the site.

Sure is

Has anyone gotten a tune from intense racing?

Intense was known to blow up your tranny.

A tb spacer is a waste because it doesn't make you flow more air and is a possibility for a coolant and vacuum leak.

Ok good deal see if I can swing the good winter deal he has going

Hey guy, why did you make 2 threads about the same topic?

Because if one gets no replies pretty sure the other will lol. I'm just looking to have a fun DD and be reliable with a few mods that's all. Ya'll's knowledge of enhancing the perf of the 3800 is far beyond me and I'm still learning so I'm trying to ask questions where they hopefully will be answered no matter weither they are the same thread or not.

depends on what you want done
