Rest of the mods are:
- L500

Loaded up the base file upon login car didnt feel right and there was no warning lights was a head scratch moment for abit then we realised who ever fitted rest of the mods trapd the vacuum line for port flaps so they where stuck closed and not opening under load.

Rectified the issue and carried on with tuning.
Once tuning was finished put it on the local dyno for power run and cars making

475 bhp & 571nm torque at 1.85bar & 9degree timing on Tesco momentum 99

Customer didnt want to push the car as he wanted a conservative map till we forge the engine and send it fully.
