So wanted to tell everyone about my experience at church's automotive. First let me explain what my car is and has.

2004 enthusiast 350z w/ 98,000 miles or so.

Kinetix v+ upper plenum
Jwt pop charger
Berk test pipes
Xo2 cat back with magna flow X pipe
NGK iridium 1step colder plugs

So first I thought I had like 330 to the wheels due to my upgrades. Hahaha rolling around town thinking I was a badass. Well I was changing my plugs I noticed my plugs were very white (means your running lean) so I thought I need to to finally do the tune. Went to church's and I must say what a great shop. Reviews say it all. Well at the end of it I came in with 277rwhp 258lbft. After reading that's actually really good he tuned it and changed the rev limiter from 6500-6900. Came out with 288.218rwhp and 269.207lbft. For a DE that's actually really good. So hope this helps people that have the same mods know we're they are.

 

dyno sheet? what kind of dyno do they use? good numbers.

 

Was it his recommendation to raise rev limit? What was gain from tune

 

Dyno jet. I dont have a scanner. I can take a picture of it and put it on here when I get home. Gains were 11whp. Said the numbers before and after. I believe almost everyone with a DE raises it with the uprev.

 

But it was shawn's idea

 

sorry to thread jack but im going to be installing my sts turbo kit in the next month or so and pretty much the only tuner i've had in mind is shawn. I've read numerous instances of people working with him and getting the best gains with conservative tunes. Ive also talked to a lot of local people here in vegas, that have had great experiences. so he is definitely very highly recommended.

 

I think you've got it wrong; Church uses a dynapack, and high reading one at that...I would know, I go to him for my tunes...

 

You are right it is a Dyna pack. My mistake. I know it was dynamic something lol

 

Her she is anywho it is a dyna pack. Stupid auto correct I was trying to post a video but my iPad is garbo!!

 

Lol so proud hung that **** up on the fridge

 

Thought it was better then my drawing of a house and family I had up earlier

 

Church auto ftw, I've gone there three times already for tunes.

 

I got mine done at there too. Why the colder plugs?

 

Well this is how I understand it.

Since I changed the air mixture (a lot more air coming in) and a lot more exhaust coming out, it changed my fuel mixture to dump more fuel to add with the extra air aka "AFR" so i required colder spark plugs to keep the fuel/air mixture from igniting before the spark fires.

Sure someone else can explain it better

 

lol. But thats what the tune is for. Now they may be robbing power.

 

No, more fuel is being dumped then "stock" so its getting hotter then stock. Also the plugs where in the car when it was tuned. So the ecu knows how its igniting. Sp?

 

Google search it. Read up on it. Made sense to me. Also seen guys do it around the forums. Church said it was the right way to do it. So.... ya idk what to tell ya

 

Just saying because I have simalar set up to yours minus test pipes and put 292-293hp. I figured you should probably have more hp than mine thats all.

 

Ya I did a conservative tune. And my motor has a lot of miles
