Ecu Remap Time & 76mm Exhaust Modifications! Opel Astra Turbo Z20let

the 76mm Astra Opc z20let exhaust needed a resonator fitting to cure the annoying rasp at higher revs, and then its time to give this bigger turbo setup some more boost, the engine is built to take over 500hp so its easy work with this setup.

[@MrLorenczo]

The car building god!

[@bevanator1007]

Love the overrun pops!!

[@leewatson939]

Top work 🤙 what turbo are you running mate? My turbo rebuild k04 hybrid oil seals are gone so looking to get something else on that will withstand some abuse and some more power.

[@alexunknown9069]

Great video mate 👌🏻

[@Alfred-xc3hc]

Aaron and boxing Saturday night ffs ' let the good times roll'😆

[@utilitarian]

All the pops 👍🏻

[@Toolsandtech868]

[@lewishill64]

Love this video, makes me want to tune my Astra.

[@Zaynite]

Oh my, that sounds amazing 🔥

[@L4WNY..]

When you do eventually get to do some flyby videos........ Can ya do them past a police station with the pops and bangs!! 😁👮😂😂

[@jamielaw9798]

great video aaron. you are a genious, when u doin a wire tuck on the evo ad love to be involved in that job haha your car knowledge is unbelievable mate are you a motor sport engineer to trade??

[@pawelkloc1]

[@bunabuna9287]

Class!!!! Sounds mint

[@Axionary]

I love this thingie 😂

[@mq1405]

i have the same car but where TF did u get that sexy body kit from, there so hard to find

[@fabiancloete1583]

Hi, love your videos. What do you use and how do you remap the standard z20let ecu

[@marcr7038]

Another good video I need to do the exact same with my 3" system. Do you not run a tank heatshild on this mate? Mines pretty much had it and I've never seen anyone not run one but if its possible I would.

[@thiagoaugustodasilva149]

Just wondering, you are using the Op-comm for flashing the ecu? Or you are using some other connector? I have an astra like yours and I'm would love to change the fuel ratio.

[@jasonjuggler3457]

Do you take your cars off the road during the winter road salting months?

[@Kolinsky19]

Hi. Can you please give me an advice on the tuning software? I can remap my GSI, but don't know all the software needed to modify the stock bin and I haven't sorted these 32 checksums. Maybe MPPS can sort all of the checksums, but not sure of that. I'd like to learn how to modify my map (crappy afr and ultra high limiter) with some "base" tuning software like TunerPro. Thanks man, I really love your work 👌

[@badboi162]

Don’t suppose you know what would cause the onboard computer (display) Not to show why oil level low or coolant ? When I drain the oil I check it and don’t warn my all the time and same for coolant not sure about other things on it as never get low on screen wash etc If I disconnect coolant level sensor then it works once then not again

[@maxkerby866]

This bloke literally knows everything about tuning and tidying engines up. Where is he from? Does anyone know if he has any social media to contact :/ thanks

[@poms8436]

He’s from East London originally now Essex . I know these things 😉. You can contact him on Instagram at officialaaronaaron . He also has a website to buy merchandise .

[@biotriffid91]

Never seen your car round this way lol have to keep an eye out for you

[@T-Wrex1864]

Forgive me if I'm wrong but isn't "pop, bang" remaps bad for an engine? This isn't a hate message rather than wanting to know more. I was always told to stay away from them because they damage your engine.

[@Bubus9ify]

Hi there, quick question please.. My Z20let with around 250 HP and straight pipe stainless exhaust with sport cat is super loud! 132 dB.. You almost can't sit in the car because of the resonations.. Will a Resonator like yours help me reduce the noise and help with the excessive rumbling? Thanks a lot! Great vid

[@fabiancloete1583]

What setup you running buddy, engine performances wise?

[@lukeandchloe]

Not a fan of the pops n bangs but the car looks great 👍

[@clfsti]

Aaron what cover is that on the evo ? And where from looking for a good one the last one I got was not the best thanks

[@aaronhenshaw6001]

Where did you get the resonator from? I need a 2.5 inch one

[@richie9777]

Even your laptop is named Unknown lol...

[@jackforsyth1999able]

You got or know anyone that has a Astra gsi for sale? Condition can be anything

[@astravxrred1085]

Do the VXRS have a 2 stage cold start?

[@dannyBtech]

very nice astra , is there a reason why you chose this 3 door style astra over the better looking bertone coupe , the bertone reminds me of the sleek calibra...

[@philiparcher8628]

Totally agree i had a 2.2 bertone coupe lovely looking car ..

[@dannyBtech]

@@philiparcher8628 i have always thought vauxhall should of called the bertone coupe the calibra mk2 , all they would off had to do was maybe restyle the front and rear lights like they did when they took the caviler and made it in to a calibra... ,,,,the bertone is easily the best looking astra and maybe one of vaxhalls best looking cars off all time

[@jasonjuggler3457]

Any recommendation on car covers?

[@Ad0akes]

A garage is good

[@patrickdonohue7719]

They just scratch the car and hold damp

[@danielmoukli4590]

yeh mate, I recommend you forget them altogether

[@Ad0akes]

Get a cheap gazebo with sides

[@user-xq1ms6of5t]

[@weejay51]

[@lucianfridrik5332]

Hello guys. I need the code for the hose underneath the air duct part GM 90423533 and engine. Thank you

[@thehomemechanic6964]
