Hptuners?

[CamaroDood]

Anyone know if Hptuners is working on a tune for the v6? I have heard loads of good things about them, maybe they'd find some more power and torque etc

Nope.. not working on it... low priority for them... doubt they will find any thing.

If memory serves me right (and mine is shot), they were working on it and couldn't find enough gains to justify production etc.

That was Diablo... On the HPTuner forum they said they were even actively looking at it...

So the stock camaro tune, must be pushing the engines limits then?

Its more like it is getting the most power out it can with the air it is flowing. You can get more air flow with things like CAI and Headers and get some improvement. After that you would need to either force more air through or get it ported.

As an example of why are engines aren't as "tunable" as other, take the last port-injected NA truck I had. That vehicle had 86.4% volumetic efficiency which was considered good. My stock LLT had 98.9% VE. After CAI/Headers/Hi-flowcats/Exhaust it went to 102.x% (and wasn't running well). Vince retuned it and it went to 109.6% VE. That is amazing! The engines are breathing machines! There isn't much room to improve without forcing more air through. You can't say the same for a car that is at 85% VE; there is lots of room for improvement via tuning, cams, porting, bigger intakes.

The engine and transmission can handle more power, we just can't develope more with out going to some extra trouble.

slightly disagree.. there is room for improvement with porting, working the intake...etc.. problem for most is going to be the cost... i have heard reports that a ported/worked over LLT made like 320 RWHP... That's why I'm looking forward to seeing bmwdon's results...

You're right. Forgot to mention porting. Basically, anything that helps flow more air will help and the ECU seems to adjust automatically in most cases.

I can't wait for bmwdon's project to finish, too. It will be nice to see one of these putting down close to stock L99 power!
