Lumpy running - Remap Time?

[bearne1]

Hi all,

Have had the Trophy since May 2009 and seems to be running a tad lumpy since I first had it (done about 20k since!). The air filter fitted is a Pipercross Viper and it also has a Samco hose. Had a Janspeed exhaust fitted with decat mod (similar to Mark Fish) at my local fabricators.

Going forwards I am wondering if a remap will sort out my lumpy idling and generally poor running. The car does not seem to have the pull as my old 172 (that had a cheapy backbox and remap). Wondering also to ditch the air filter and go back to standard setup with a performance foam filter?

Any help will be greatly appreciated, thinking of the RS Tuner but not 100% sure.

Id def recommend putting the stock air box back on, but while your at it give the throttle body a good clean. If the trophys never been mapped id def recommend it, the difference for a N/A car is quite amazing. Not much more power but the drivability and mid range torque really does transform the car.

The map also smooths out the idle, but if your looking at other mods (matched inlets et) then get them done and then go see matt @ TDF for a custom map

If it's not running well, I'd get someone to check it over, make sure it's healthy. I wouldn't think of a remap as a solution.

It is healthy, just not running as I'd like it! I think the Viper is the problem and will consider moving back to standard filter. The cold air feed to the acoustic is not even joined to the viper!
