The Mk1 Astra is lovely
Hats off to you my friend.
AngelWorks install looks very very clean & tidy.
Does that run OEM ECU?
Can you retain A/C with the ITB kits?
Not OEM ecu, no.
Can you retain Aircon? Yes, if you want to squeeze it in and have a pointless ITB install, or have a rather thick wallet to allow you to keep aircon without compromising the ITB install.
