Would Mail Order Tune Be Sufficient? I swapped my LS1 shortblock for an LQ4 shortblock, but everything that was in the LS1 went into the LQ4, cam, heads, headers, etc. The LS1 was previously tuned, so in this case, would a mail order tune by Frost or similar be ok or should I still get it dyno tuned? I'm in SE MI so I know there are some options around me, just wondering if this would be ok to do since nothing but displacement changed.

I'd get it retuned, if you can get it custom tuned even better. has the compression ratio changed? seeing that you're now running LQ4 that are dished pistons as opposed to the ls1 that weren't, it'll have some impact on combustion and AFR in my opinion.
