I agree that without a doubt its all about the tune... U could have Watever brand ems n still blow up so as long as ur tuner is spot on u should have no issues... Good luck.....
if it makes your feel better about spending $2k+ on an EMS to make >400rwhp

Nothing against haltech.... I would love to play with a haltech...uprev always leaves me wanting more control and the undocumented 'features' are always a joy. But for the $$ it works for me, and I like having the electrical system as stock as possible given it's still gotta pass emissions...no CEL, ect.

Im not knockin ur UPREV and wat is affordable to u.. If thats wat it is then go for it. Jus didnt wanna mislead someone by thinking that UPREV was a really good choice wen its time to break the 600hp limit. Most ppl would prolly upgrade by then, my point is y spend $800+/- only to later go n buy a better ems such as pro efi or haltech. And most guys are never satisfied with their first power gains and wanna upgrade sooner or later. So for me the choice was clear. The 2k price tag didnt set me back at all... But I wont be buying another ems wen I decide to build my new block which BTW is already in the works!
As for electrical system being "As stock as possible" Im not sure wat ur referring to? I have no issues with my Haltech. Ive run it N/A n Boosted. My electrical system is flawless. Everything works as it has always worked. The car idles better than stock. Further more I also had my ecu flashed with UPREV to clear out any possible codes n lock them out permanently.
Listen I appreciate every one who does their own work and has the integrity to do so. Sometimes these forums mislead ppl who are lookin for answers then they make a thread n dudes bash them talkin about hit the search button.. Chances are that person already did n came across a thread like this but left wit an unclear answer. Every one has their opinion, and u kno wat hey say about opinions.....
Bottom line is get wat u can afford I guess....
U said it urself "uprev always leaves me wanting more control" Do it right the first time.
Ray.... Grumpy Haltech owner!

I don't think trying to estimate your HP is gay, nor is it uncommon. Typically, it is phrased as "what do I need to do to make xxx hp?" At least the OP has put forth some effort on his own to arrive at his estimation.
Anyway, it is tough to come up with a "guess" without knowing ALL of the supporting mods, for example the size of the exhaust, the size of the I/C, whether downpipes are being used, etc. Moreover, tuning plays a huge part in the final results. Some tuners are more conservative than others. Also, it depends on what dyno you are testing on, and the ambient temperature. A DJ dyno will read much higher than a DD dyno.
On a DJ dyno, the OPs guess may be fairly close if he is running downpipes and a 3" exhaust with a moderately conservative tune. On a DD dyno, maybe not.

I was talking to a buddy of mine and we were thinking the exhaust could be a big reason for that 25rwhp difference between our cars. I'm not running any cats at all and the Greddy turbo ti-c exhaust is a pretty straight through exhaust as well. Are you running the open dumps or did you recirculate them into the exhaust? I'm not an expert but you can normally get a good estimate of hp with trap speed and you're only like 5mph slower

Well Dynostys dyno dynamics dyno reads very low and I was told my car would make close to 450 if it had fans on it. Any other dyno close to or over 5

Yeah I was tuned on the same dyno as frosty and made 454whp and trapped 124mph last year.
Yeah I guess temp. and fans and all that other stuff would make up the difference. Thats crazy an exhaust system is making that kind of difference. How long have you had the twins on? Any plans on building the motor in the near future?
