Default opinions please

Please let me know if these are normal results or what. I have an 07 MN6 z51 that I had a shop put on kooks 1 3/4' lt headers, 3x3 high flow cat xpipe, corsa extreme pipes and halltech intake and custom tune. I am not sure what kind of dyno or SAE, std etc they have, but the results were 368 hp/ 361 tq and this is in phoenix elevation on a 70-75 deg day. Is this normal? I guess I was expecting a bit more out of all this put together. I am jealous of these guys getting over 400hp with only a ported manifold it seems.

It looks about 7-10 low for both, which could easily be attributed to type of dyno, weather, etc. or any combo there off.

Well the only thing there that would help at the dyno are the KOOKS HEADERS. Things like catbacks and even cai add very little sitting on the dyno You did not mention anything about a tune which would give you perhaps 378 with the current setup. Nobody is getting 400 with just a ported manifold. Also SAE would read slightly lower than std because of the correction factor used. usually about 5 hp/tq or so.
Dont be discouraged but find what the base numbers were then take it from there. It takes pretty much of all the bolton mods and a really good tune to get to 400 but it can be done.

You did fine ....Don`t get wrapped up in the dyno numbers . Go make a couple of passes at the 1/4 or 1/8 tracks to see what you really gained .

Your HP/TQ is right on for an LS2 on a Dynojet 248 SAE corrected. The 400 HP claims are LS3's or other Dyno brands (or BS).

Not to worry my 07 had the same numbers you posted with the same mods. Dyno Jet in Denver, Colorado at 5,200 ft. of altitude SAE corrected.

Default thanks guys

as always, the people on this site are top notch. I appreciate the advice and the votes of confidence. I didn't know what to compare too. I don't know much about dynos at all, but the sheet didn't say much about it either, only the axis labels were SAE. Don't know what the car started at because I live 5 hours from the tuner and they started the installs in the morning and then had a custom tuner come in the afternoon. He seemed to know his stuff, this is a vette specialty shop and everything seems to run great.

I love my car, but did buythe extended warranty and want it to last, but would love more punch. I can't really tell if I got a whole lot out of the mods, but it is more responsive. Never a complaint from 0-70, but from 70-120 takes to long IMHO. Haven't timed it though, just always WOT. Great car and no complaints. thanks again for the the comments.

His isn't low your's is high. There isn't another LS2 on this board that got 396 with just headers and a CAI.

Just got my results back on my Stock, C6, 05, A4. dyno SAE 350.3 RWHP and 355.5 RWTQ. Dyno was done before the mods go on.
