I never said that i was at 330whp hats just what my tuner said i should be at. I have no idea how much power im pushing and i wont know until i dyno in the spring with my new clutch. I have numbers in my sig but those are with bolt ons and JUST the stage kit BEFORE the HP tune

 

Meaning there are multiple competitor tunes available vs. buying a BSR tuner.

 

My dad can beat your dad up.... Come on, all tunes are just about the same and all cars are different. One vehicle will be 5-10 HP lower or higher than the next in some cases. I will get mine dynoed when I can to see where I'm at before and after updated tuning.

 

Camaro98, I agree this does seem to be quite the pissing match. Like I said it's nice to have some numbers to compare, but putting those to the test on a track can be quite a different story. I too will post numbers after I get set up with my Stage 1 and bolt ons. I just feel like my Dyno this and my Dyno that sounds kinda lame if that is your end all be all. Good to compare with.

 

I cant wait to hit the track. The only reason i didnt go this year is because the clutch doesnt like me at all since the car got tuned. But ill be going for sure

 

Thanks.

 

Shoulda bought an auto......

 

Yeah, the SOB xeroxed my time slip. I ran the 7.1 in my Tercel with a cold air intake and a big wing.

 

That was the 1 mile time right

 

I believe the Cobalt LNF and the HHR LNF represent an equivalence class for the purposes of dyno measurement, where vehicle weight and aerodynamics have been mitigated by the fact that the car isn't actually moving. Since they both use the same motor, same E69 ECM, and same Getrag transmission, dyno numbers should be comparable/interchangeable.


I understand your anecdotal experience may have led you to believe this, but it's simply not accurate, and without you having actually analyzed ALL tunes, simply making that statement is a gross generalization, not based on fact. The fact is that most tunes emanate from the HPT product. As such, most tuners are limited to the (appalling lack of) table data available through the MPVI. However, not everyone is using the HPT MPVI... Trifecta, for one, has done his own bus traces, and reverse engineered areas that HPT simply hasn't put the resources to opening up (it's not that they can't, it's that they have, sadly, put their business priorities on other platforms). As a result, the Trifecta tune (whether "better," "worse," or just "different") is absolutely NOT "THE SAME" as those emanating from HPT-based tuners.

Additionally, I have seen "for sale" tune files from 2 different HPT-based tuners, both designed for a bone stock LNF motor, no Stage kit. A simple diff exercise (HPT VCM Editory has this function) between these 2 tunes clearly indicates they are absolutely different in most ways-- one guy is tweaking cam timing, the other is not; one guy is modifying Desired Airload at least 10% variant from the other guy. These things do indeed have an effect... and the "butt dyno" doesn't accurately catch this, especially when you're trying to measure 2 cars side by side. In my youth, I could drop a .502-.504 light pretty consistently. Today, however, when the tree goes green, I'm probably still tuning in a radio station and adjusting my mirrors... in other words... 2 drivers cannot be used to make a comparative evaluation of 2 cars with 2 tunes. That's _2_ many variables that are out of your control. The proper experiment requires equivalent vehicles in equivalent environments, running different tunes. Ideally, those equivalent vehicles and environments would be the SAME car in the SAME place, but that's a luxury the community doesn't really have... however, that's what the construct of equivalence classes are for.
