The IHI IS38 turbocharger — factory-equipped on the MK7 Golf R and Audi S3 — is the proven direct bolt-on upgrade for GTI, GLI, and 8V A3 owners looking to step beyond Stage 2 without committing to a full big-turbo build. iE’s IS38 Map Pack is a custom ECU recalibration developed specifically for this turbocharger on the GTI/GLI/A3 chassis, delivering Golf R-level performance with the fast spool, smooth delivery, and daily usability that makes the IS38 upgrade such a compelling option. 

FROM SPORTY TO HOLY $#!%

Real horsepower gains without sacrificing safety only happens when every detail is dialed in. That’s what iE does best. The iE IS38 Map Pack upgrades your GTI’s factory engine computer with custom programming built specifically for the larger IHI IS38 turbocharger. Smooth, predictable power with none of the harshness, lag, or unpredictability of generic setups. More power, stronger acceleration, and a pull that keeps building long after the stock turbo gives up.

Golf R performance levels in the GTI. GTI spool. GTI fun. 

ALL THE UPSIDE. NONE OF THE TYPICAL COMPROMISES.
