So i got an rs1800 (mk3.5) its got Green cotton induction with cold air feed, de-cat, ashley full exhaust system, ashley 4-2-1 manifold and super chipped.
Basically it wont even beat a corsa 1.6 with roughly 120bhp on the drag, we swapped drivers and had several runs.
The car runs nicely with no apparant faults. Now im wondering weather theres somthing subtlely wrong? does anyone no anything that could help with my problem or any other mods e.g port/polished throttle body, or any inlet manifold mods that could help?
I reallllly wana sort this because i would hate to have to get rid of it because other then its speed i love it.
all help/advice would be a great help. cheers en'.
