^^^yeah, tell me about. That's a huge clean-up in performance #'s.

 

Both of those dynos were from a pre Rev Up engine. 1/2 spacer has nice top end though.

 

I just finished self-tuning my car on the street with an LM-1 wideband. The first time I put the car on the dyno with the UTEC I gained 4hp from 4 runs of tuning, and that was fuel alone. I made 253hp on a DynoJet. Since adding test pipes and retuning, im right around 270 wheel now. Thats not a quoted dyno number (not enough time or money at the moment), but Im sure the car is very close to that. I dont even have a plenum spacer either, which bump it up 5 more or so. With the right tuning, even on your own, you should get at least 10hp. Im sure more is possible, just depends on the car.

 

I got about 23-24 peak hp from mods in my signature and tuning, and much more area under the curve

 

The 2nd Dyno sheet is actually my Z. It's actually a non-rev engine with 5/16" spacer. For more detailed mods on my Z, click on my sig below.

 

i got 270hp264tq on i/h/e/test pipes/ spacer and utec tune, on a DJ...i have a 03 so my hp gains stoped at 6k. i was happy with those numbers, waiting to see what cams will do

 

frankly, it's too broad of a question to even answer

 

I've spent at least an arm and half a leg for 254.7 whp/ 241.4 lb/ft dyno tuned by Sam at GTM (Dynojet numbers) on my AT. It's funny that if I'm talking to some Joe on the street, who's not dyno wise, I use the Dynapack numbers instead. Hmmmmmm lol.

 

Ive got 253rwhp on a DJ with TP and Popcharger

 

I gained 20rwhp on the tune alone. Note that my car was running like crap after headers & high-flow cats were added.

 

this is true......i gained 30 hp and 35 tq from my tune.....with all my mods before my tune i was at 240 hp and 230 tq........amazing what a tune will do

 

From what I've observed, it really depends on 2 things:

1) How well your car adjusts to mods. (the better you car adjusts to mods, the less you will gain out of the tune, and vice versa)
2) How capable your tuner is.

 

true, my car was rich before tune (11.5).....but the first guy who tuned it sucked!!!!!! only got 247/235...i took it to an LSX shop, it was his first time tuning a z or utec and he got my final numbers outa it....probably the best numbers for my limited amt of mods in my area..and you know who is in ATL. gothchick has some stout numbers as well but that sneaky ninja can rev higher, which is my z's problem

 

I thought that even in the 2006 model year, 5ATs came with the "non-revup" engine, and only the 6MT came with the revup.

edit: someone already said the second Z is non revup with 5/16" spacer , whoops
