Bring your M52 to life with this fully tuned, daily driven, and track tested performance chip. The SSSquid Tuning performance chip is the most complete tune on the market, with every aspect of the mapping being optimized from idle to wide-open-throttle.
This tune is specifically intended for M52B25 engines running without a MAF sensor*, instead utilizing only IAT + TPS to tune. This tune works with the stock Bosch Motronic 075, 402, 403, 413, and 506 ECUs.
These tunes are region specific, and a tune for sea-level may not operate as ideally at high elevation. The use of a well working stock EGO sensor will help the ECU adjust for any necessary fuel changes.
*IAT sensor should be retained for best results, but may be removed. If you choose to remove the IAT sensor, your tune will be region and temperature specific, as air density is directly related to those factors.
This chip is compatible with the following engines that have been converted to or swapped into OBD-1:
- M52B25-TU (M52TUB25)
- please specify in notes
++ Denotes modification-specific limits. We will recommend a rev limit based on your engine modifications, but it can also set according to your request!
