    no offence but sounds like you wouldn't of been happy unless she was pumping out 300rwkw as everyone has pointed out you got exactly if not a tad more than the norm from simple bolt ons and tune.

    HM headers definitely aren't ****, some of the best gains on the market. At the end of the day it's just bolt ons - there's probably piss all difference between them, difference in sound probably with the better quality headers.

    If you've got issues give them a call.

    It was your call, set of fancy extractors won't give you an extra 50rwkw if that's what you were expecting.

    I haven't called yet as the car is booked in for a 98 tune in a week, so before I passed judgment I have driven it 250 + kms, had a mechanic who's modified many a machine drive it before and after tune without telling him what I had done, to get an unbiased opinion and he said exactly what I was thinking.

    These are not the only issues the auto is far too aggressively tuned (I said I didn't want that) and doing strange things like driving idling (no throttle)in 3rd manually changing to 2nd and having the car rev to 3000rpm for 3 sec and then actually changing.

    I was planning on going to meet at port melbourne tonight for opinions but as the car is throwing a code don't really want to drive it. anyone with an OBD2 SCANNER?

    Well I was going to go, but you already got my opinion. You went in expecting far to much and got what is a pretty standard tune and figure.

    Do you have some more info and pics of the intake they used.

    another quick question, is there a reason why you didn't use an OTR. The 250kw with bolt ons is about right, mine from memory got around the same[6l auto]

    I was expecting:

    1. The car to drive like 85% of the HARROP, WALKINSHAW, GM MOTORSPORT DEMO CARS bearing in mind the my catback, It has nowhere near the throttle response, or torque. these cars were on 98

    2.about 5 to 10rwkw more than 426cuda (260rwkw)who had a gain of 30kw after fitting hi flow cats and a tune to the otr, hsv extractors and gts catback

    3. To have better throttle response than a stock 150,000km ve ssv auto (my brothers car)

    4. what I was promised : HM Headers = better than HSV, :SIDEMOUNT CAI = no different to otr

    sidemounts VS OTR is a personal call have read of heaps of people with a preference but OTR seems to be the decision if you are just chasing dyno numbers, as far as throttle response yes that should improve but do you know what sort of fuel he was using at the time (your brother you are comparing to). LOTS of variables and not enough people being clear with the tuner they choose after what they are looking for. From the outside it sounds like you are just chasing numbers and maybe the tuner has done all he can to try and please you with them, sit down with him and explain what you want from the throttle and maybe they can match it better.

    At that power level 10rwkw is less than a 5% variance, it's nothing. If it makes you feel better take it back and get them to strap it down weak like most places and you'll have your 260rwkw sheet.
    I find it hard to believe that the throttle response is worse than it was before.

    OTRs would probably give slightly better throttle response, they heatsoak badly though.

    I've never understood why some people are so number obsessed when dyno tuning a car with an otr and exhaust. in a car that has basic bolt ons its all about seat of the pants feeling, mine doesn't make bulk power[under 250rwkw from memory on 98] but is an absolute joy to drive has nice acceleration/torque down low.

    simple math 5-10 + 260kw = 265-270KW

    I am losing on both counts the car is a disappointment to drive it doesn't make the numbers and i think the blue line is stock. on average a vf SS with auto makes around 215rwkw on 98 on e85 220rwkw good possibility

    you guys are unreal you don't see anything wrong the check engine light funny no comments there.

    check out these photo's and tell me you don't see anything wrong

    anyone who has similar mods and wants to drive my car back to back feel free if its me i'll shut up. why is it you all just assume there is nothing wrong?

    photo's

    CAI :Looks pretty!! too bad its not actually sealed off from the engine bay has no cold air feed and the actual pod filter is rammed up hard against the inner wheel guard and chassis rail in a closed off void behind the bumper.

    EXTRACTORS : have virtually zero collector before stepping down to a 2.5 inlet cat yeah awesome for scavenging, gas velocity etc (no arrow spike, no length to secondarys for torque)

    what do the photos prove?
    the check engine light could be lots of things not just something the tuner has done, could be a bad coincidence but def needs to be looked at.
    Honestly mate sounds like you wanted the world but on a shoestring budget and if ya wanted it like a WP kit why didn't you just get that one ?

    in your first post you mentioned GMM and then went to APS, any reason for this?

    As for having "Less throttle response, less torque until 4000-4500rpm" is this just putting your car in D and driving or is this in sports/manual mode on the transmission.

    As for those pics, exhaust looks right, but the intake looks like a throw together design. If i was you id consider getting an otr and trying to sell that intake.

    Because I do my research why would I pay $6500 for the same gain as $2500 approx.

    I paid the $3350 a grand extra for a gain I never received

    Its not about a shoestring budget (I could drop another 10k if I wanted it supercharged)its being smart and getting value for money not wank factor

    I don't really care what it sounds like its better than stock

    Yeah mate, that's ****. I thought it would be brilliant, maybe there's more to the dyno report as well btw.

    I was going to GM but according to them there is no gain on E85 and mafless tune (Danny who answers is rude and not very knowledgeable) APS was recomended by PIR4TE and i had only read positive things
