Diesel performance launches that show up at the dealer before the dyno cools.

Heavy-duty diesel performance is the most variant-dense category in automotive aftermarket. A single transmission rebuild package — say, an ATS Diesel 68RFE Stage 3 — typically ships in 24 distinct SKUs across 2WD/4WD axes, three performance stages, and four model-year ranges. A high-output fueling system might cover LBZ vs LMM vs LML ECM calibrations on Duramax, with each ECM variant requiring a different tune file, different install procedure, and different power claims. Generic e-commerce platforms render these as 24 dropdowns no customer can parse; generic marketing tools can't extract the structure at all.

NPR Grenade pulls variant data from your Shopify, BigCommerce, or Web Shop Manager product page and groups variants intelligently. Common option values are extracted as variant-group headings (e.g. 'Stage 1 — 6 variants' instead of '2WD / Stage 1 / 2007.5-2011') so the rendered fitment table is scannable on the landing page, in the PDF, and in the email. Install-guide PDFs linked from the product page are pulled through automatically and attached to the release; dealers receive the technical doc with the marketing packet, eliminating the follow-up email cycle. ECM compatibility per tune is rendered as a per-variant compatibility section so dealers don't ship the wrong file to the wrong truck.

Dyno spec tables — HP/torque deltas, EGT improvements, fueling curves — are extracted as structured data from your product description and rendered cleanly in every output format. The PDF data sheet looks like an OEM-quality spec sheet: brand-consistent typography, structured spec tables, fitment matrix, dyno chart placement, install-summary callouts, and dealer contact block. Diesel performance shops, dealer networks, and fleet customers receive a packet that reflects the engineering depth behind the product — without your team manually formatting 24 variants into pipe-separated chaos.
