How accurate is the Supra MK4 tuning simulator?

The simulator uses real-world dyno data and advanced algorithms to provide approximately 90-95% accurate power estimates for common modification combinations. Results may vary based on actual parts quality, tuning expertise, and environmental conditions.

Can the simulator predict turbo lag and spool characteristics?

Yes, the simulator calculates estimated turbo spool time, lag characteristics, and power delivery curves based on turbo specifications, engine modifications, and boost settings. This helps in selecting the optimal turbo size for your goals.

Are the cost estimates in the simulator up to date?

Cost estimates are updated monthly based on current market prices in India for both new and used parts. The simulator includes options for different brands and quality levels to provide accurate budget planning.

Can I save my virtual builds for later reference?

Yes, you can create an account to save unlimited build configurations, complete with modification lists, power graphs, and cost breakdowns. Saved builds can be shared, compared, and modified at any time.
