LS1 tuner recommendations

[ian_uk1975]

Running a highly-modified FI LS1 383 stroker on a stock ECU. Any recommendations for someone to map it? I'm familiar with John Sleath, but he's up North and I'm in Northamptonshire.

Top Cats Racing? Pro Tuners?

Not sure if these guys will be able to help.

If it’s FI on a stock ECU, are you running it on a custom operating system by either HP Tuners or EFI live?

If HP Tuners then I think Wortec could be an option.

If on EFI Live then https://lsperformanceparts.com/ is an option and they work with Luis Sola to tune. There is a LS Remote tuning – UK group on facebook associated with them, it could be worth asking there?

When I had mine tuned (modified LS6 in a RX-7) I went direct to Luis and he put me in touch with LS Performance to purchase EFI Live. This was a mixture of on road driving and a Rolling Road session with Luis remoted into the laptop to refine the tune.

I’ve heard Protuner in Coventry use EFI Live but have no experience of them.
