Rather fewer will fit it properly, tune it to your site's limit and hand it back working. We run HPA ourselves every game day, on the same platforms we sell, so diagnosis comes from having had the same problems rather than from following a manual.\u003c\/p\u003e\n\u003cp\u003eWe work across the three main engine ecosystems. \u003cstrong\u003eWolverine\u003c\/strong\u003e — INFERNO Gen2 and XTS conversions, BLINC and Bifrost programming, MTW and Article Series servicing. \u003cstrong\u003ePolarStar\u003c\/strong\u003e — F2, JACK and Fusion drop-in kits, plus the fully mechanical Kythera. \u003cstrong\u003eGATE\u003c\/strong\u003e — PULSAR S, D and the PULSAR H hybrid conversion, including TITAN II and ASTER II Bluetooth setup. If it runs on air, we can fit it, tune it or fix it.\u003c\/p\u003e\n\u003cp\u003eBook the job you need below. Each is a fixed price for the work described, so you know the cost before you commit rather than waiting on a quote.

Not every AEG will take every engine, and the check takes us two minutes if you ask. Details are in the compatibility section below — and if you are at all unsure, message us with the make and model before you buy.
