lol..I don’t have that problem..here in England Volvo drivers are perceived has old men who are past it and the cars themselves not very sporting!...The AudI and BMW crew can’t believe their eyes when they look in their rear view mirror and all they can see is my number plate ..so funny lol..
Don’t bring cost into it!...if you like the car then spend some dollar cos you’ll be the one enjoying it..My mate thinks I’m daft putting money into my Volvo but I like the car..he thinks I should invest in a BMW535 twin turbo diesel..they’re just short of 300BHP standard and there’s a bloke in Scotland who can get well over 500BHP and over 700ftlb of torque out of them making them a M5 destroyer..but those cars are known for being fast whereas my Volvo isn’t..:)

I just feel its unfair to give up on your favorite car just because it doesnt fit into the generic sleeper/tuner/racer profile. After constantly being shut down on multiple occasions by tuning garages for the same reason you said "why invest in that junk" i just gave up.

I really like my car and it's in really good condition, i just want to keep it until it falls apart with no chance of repair. My brother used to work in a garage really far from me and ill contact them to see if they can help me out sometime in the future. No rest for the wicked i guess lol

Im curious to see how your results pan out, for some reason i recently got an offer for a 180 gti engine and a set of forged internals which is weird since i didnt really ask for any of that. I wanna see what the hdi has to offer first :Đ
We ended up with 191BHP which was a bit of a letdown but comparing the new power curve with the old one we got more than +40BHP from 3,250RPM upward..the hybrid turbo was maxing the map sensor out,we have found an upgraded sensor which will allow more boost so we should see over 220BHP when we get that fitted?..The journey continues..lol

Don’t know yet..when the map sensor arrives and fits as hoped without any modifications then I’ll book her in..

I feel dumb for being excited as if its my car in question :D
Well she’s been remapped..bitter sweet to be honest..Only made 200BHP!..the fuel pump was maxing out after 4000RPM!..we need a bigger fuel pump..surprisingly the injectors were well below tolerance?...so the journey continues.. lol..

Stock injectors and stock fuel pump...I’m told there is a bigger fuel pump out there that was fitted to a big engined Isuzu 4x4 that Will fit directly?...apparently?..lol..

I’m not very computer literate?..I wouldn’t know how to upload it if I could..lol..it sounds good though,not too aggressive..Then other half doesn’t complain so it can’t be that bad?.. :)

I just remembered something, there is black smoke from bad tuning and too rich fuel to air ratio but i saw black goo/watery something from straight piped diesel cars that are somewhat modified. It tends to fly out of the exhaust like the cars way of coughing out blood... Is that a future issue or just plain water mixed with exhaust gases?

No idea on that one?..mine certainly doesn’t spew any goo or any other substance out the back of the exhaust?..lol..

Figured something like that would be wrong... Sometimes i feel like if people would be more mindful of their car tuning, especially diesel cars, they wouldn't be on a bad rep mostly.

The methanol/water injection kit has been a good upgrade.it actually improves the reliability of the engine by bringing the intake charge temperature down considerably..

I've seen lots of methanol combos, i wish i could do something as complex as that buuut it's never gonna happen. Im considering something like a dual turbo setup (smaller one spooling up a slightly bigger one to eliminate turbo lag) with a bigger intercooler these days, but i should probably stick with just a single turbo like gtd1244vz or gt1544v, still planning my tuning route lol, what do you think?

None of my Diesel modded vehicles belch Black smoke upon hitting the loud pedal. All have modded exhausts.
1.9T5 (upgraded to 2.0ltr, Alisport FMIC, Pipercross dry filter,) exhaust done by Infinity (Bristol). 3” from down pipes (decat) to back section where I can then either run a single can squared oval or twin can 5” cannons. The cannons are a little more free flowing than the oval. Both are loads better than the standard. You can hear turbo spool and variable vane action (turbo bark).
It’s essential to remap (IMO). To get the best from an exhaust. My mpg increased from low to high 30’s and the driving experience is loads better. But most importantly NO smoke and it passes the MOT well within the requirement.
