I'd go HPTuners over Trifecta personally. Several people have had issues with the Trifecta.

Once I get some coin saved, I'm going HPTuners.

Just call me crappy panties.........

When she was boosting 28, it was fun.

I was originally gonna do hpt because of these issues and also because there is a tiny bit more power you can get out of hpt. but I know Vince @ trifecta has CUSTOM tuned more LNF's than anyone in the world. I have yet to see an engine blow with a trifecta tune. (Can't say that for hpt)... Vince can give you decent power with piece of mind.

But yes, I agree HP tuning is superior.

I'm gonna have to ask to try the "crappy panties tune" lol

If I understand this correctly the path to maximum performance is with an HP or Trifecta Tune in conjunction with the 3-Bar GM Sensors and Connectors with the HP being a slight performance edge.

I think this is going to work well for me because here in the Phoenix area the Tuning God would be Charles Hendrickson (of “Pinks” fame) the owner of Pro Dyno and he prefers HP.

Thanks again for all the great information on here as I would not have known about the advantages of the GM Sensors and Connectors

I want to ask one more time, only because Trifecta may be in my Christmas budget So sorry if this is an annoying repeat.

If i want to order the sensors for the tune, I need to order:

(2) of this part # (3 bar MAP sensor) http://www.crateenginedepot.com/3-Ba...10930C690.aspx

(2) of these seals, (one per sensor) http://www.crateenginedepot.com/O-RI...98-P17760.aspx

and (1) of these harness adapter kits? http://www.crateenginedepot.com/Coba...0H-P17740.aspx

So, if I buy and install these items with the tune, that's all I need?

I'm thinking Trifecta may be in my near future, can't wait! Thanks for the help!

Yup thats it. When your order your tune make sure trifecta is aware that you do not have GMTU programming, just the 3bar sensors setup being installed right before tune. I would suggest ordering from BNR(bad news racing). they have a special goin right now for the premium tune w/cable here:

You could also request an ECP tune so you would be able to run this VTA BOV that replaces stock BPV:

I would advise getting an extra set of O-rings. The cost is minimal. You'll have some spares just in case.
They usually don't go bad but if something happens you'll be prepared.
What could go wrong? Forgetting to trim the tab on the lower sensor which doesn't let the sensor seat correctly. Result: damaged O-ring.

Get some spares.

I've heard from Vince and from Bad News Racing, sounds like if you go for the tune and the cable now, then if you get the sensors later they will retune for you as part of the original purchase. A great deal IMO!

This is the path I'm thinking of - get the fun of the tune right away and add the sensors later as funds and time allow.

You will be happy with the increase in power.
